Definitions
- the invention relates to a method and a device for controlling a fluid delivery system, each consisting of at least one pump, a consumer and a valve as an actuator, wherein pressure and flow of the consumer can be controlled.
- actuators or actuators preferably valves or valves with, for example, electric or pneumatic drive, also known as control valve or valve with actuator used.
- Their adjustable flow resistances influence the volume flow and the pressure in the system.
- pumps are the most important components of a system because they cause fluid movement.
- centrifugal pump with drive in most cases an electric motor with frequency converter, is the standard solution in many application areas.
- a regulation of process variables by means of a pump can be carried out via the pump speed.
- the stroke or the valve or valve position the flow rate of the pump and the pressure associated with it are influenced by a speed change.
- the proportion of variable speed drives in process engineering plants today is about 20% to 25%, these are rarely actively involved in the process control, but rather used for static operating point correction of the pump.
- a variety of applications include control tasks that require, for example, a high control range due to the process variables.
- This task can be achieved by the sole control by means of the pump on the one hand and by the sole control with one armature as an actuator. on the other hand not be realized.
- the combined use of pump and valve with associated control opens up new possibilities in process control.
- the combination of the devices makes the controller design more complex, since a multi-size system with 2 inputs must be considered.
- dead times frequently occur in process engineering plants, which additionally complicate the control.
- Object of the present invention is to develop a control concept for a system that allows the independent influencing of the prevailing in the plant two process variables pressure and flow rate at a consumer.
- the system provides for an arrangement of at least one pump, consumer and valve as an actuator.
- the object is achieved by the features of claim 1.
- the control target achieved in the controller design allows a high control dynamics despite existing dead time, a hitherto unattainable low tendency to vibration of the controlled variables and a high stationary control accuracy. For this purpose, a decoupling of the controlled variables pressure and flow rate takes place at a consumer.
- Modeling has assumed that a flow is balanced at an inlet e and at an outlet a of a fluid delivery system, that is, there are no appreciable changes in flow rates across the cross-section of a connecting conduit system. This is the case if in the considered areas a line cross-section is constant and a friction influence of tube walls is small. In the area between inlet and outlet, a three-dimensional flow profile is permitted. Under these conditions, the flow can be described by the flow quantities on a mean current thread according to the current thread theory. The Bernoulli equation applies here:
- L denotes the length of the pipeline along the streamline between points e and a.
- the model of a used test bench provides the simplifications:
- the dynamics of the actuators i. of pump and valve, a crucial factor in the overall dynamics of the plant.
- the actuators used have subordinate controls which precisely adjust the manipulated variables of stroke H of the valve and speed n of the pump to the specified setpoint values.
- the dynamic behavior of the actuators is modeled in each case as a delay element of the first order. For the dynamics of the actuators follows
- the manipulated variables dog n influence the relationship between the process variables.
- the relationship between the differential pressure Ap v and the volume flow Q of the valve depends on the medium used, the flow coefficient K vv and on installation and flow conditions. As fluid water is used and assumed turbulent flow and standard installation conditions without fittings. Then the context applies
- equation (9) was analogously in the standard work by C. Pfleiderer, The centrifugal pumps, Springer Verlag, 4th Edition, 1955, indicated.
- the naming of the variables is based on a publication by R. Isermann, Mechatronic Systems, Springer-Verlag, 4th edition, 2008.
- the state space model of the system can be used with the states Q (t), H (t) and n (t) as well as the inputs H so ii (t) and n so u ( t) are derived.
- the pressures in (4) are eliminated by inserting (7), (8) and (9).
- the output quantities according to the definition of the control objectives:
- a controlled system is considered coupled if an output y t is controlled by a plurality of manipulated variables Uj.
- the decoupling controller ideally consists of an inverse inverse coupling between the reference variables w and the manipulated variables Uj.
- each output ⁇ is dependent on the action of the controller only by a reference variable w.
- the couplings in the system can not be derived directly from the state space representation (12), since the manipulated variable u usually only acts on one of the higher derivatives of the output y.
- the first step of the controller design is therefore the calculation of the derivatives, which explicitly depend on the system inputs.
- the Lie derivation is introduced for the sake of simplicity.
- the Lie derivative L j h t (x) describes the derivative of the function h t (x) along the vector field f (x)
- each command variable w acts only on the output variable y_ * assigned to it, and equation (19) can be specified line by line.
- each controlled variable is to be influenced independently of the others only by one input, the number of inputs and outputs must be the same.
- decoupling can make part of the system unobservable.
- the unobservable part of the system is called internal dynamics and is a system property whose stability is required for the realization of the controller. It has been recognized that an unstable internal dynamics can lead to unlimited growth of internal states and therefore violation of manipulated variable limits or destruction of the system.
- a state controller for linearizing the I / O behavior is designed for a dead-time-free SISO system (single input, single output).
- the state variables required for the control are determined by a deadtime-free model of the open route, by C. Kravaris and R.A. Wright also referred to as "Overall State Predictor.” Due to the present MIMO system (multiple input, multiple output) and the fact that the open loop dead times are not the same for all outputs, some extensions are made.
- the manipulated variables can be calculated without the influence of dead times.
- the decoupling of the outputs generally requires a synchronous change of the system inputs. Since the components of the considered system have different dead times, cf. Fig. 2, the decoupling is disturbed by the direct specification of the calculated manipulated variable. To prevent this, the input of the actuator with the shorter dead time is additionally delayed, so that the dead times of both actuators are the same. By means of such dead time compensation, synchronization takes place at the outputs. Furthermore, a modification of the feedback in the outer circle is made. Similar to the classic Smith predictor, it is not the output that is returned but the difference between the measured and the calculated output.
- the inner control loop consists of decoupling controller and model the prefilter V (x) is designed for stationary accuracy with respect to the reference variable w
- the output of the distance y s will differ from that of the model y m .
- the difference e of the two outputs is returned to the controller input.
- the command value w can generally be passed through be specified.
- the regulated system is first tested for leadership behavior.
- the combination of valve and pump control valves has given rise to new degrees of freedom in process control.
- the controlled variables pressure and flow rate of a consumer can be controlled independently of each other.
- the control concept was successfully implemented and verified on a test bench with dead times. Decoupling throughout the work area was successful and model error errors could be compensated by the modified Smith predictor.
- Fig. 1 is a model of the test stand
- Fig. 2 is a state space model with dead time
- Fig. 3 shows a structure of a decoupling controller
- Fig. 4 shows a Smith predictor
- Fig. 5 shows an extended Smith predictor (after [6]), the
- Figure 1 shows a model of a system which provides an arrangement of pump, load and valve as an actuator, wherein in this embodiment, the serial arrangement has been selected.
- the transfer of the method to other arrangements of pump and valve / valve are also possible.
- the modeling assumes that the Flow at the inlet e and at the outlet a is balanced, that is, no significant changes in the flow variables over the cross section of the connecting line system occur. This is the case if in the considered areas a line cross-section is constant and a friction influence of tube walls is small. In the area between inlet and outlet, a three-dimensional flow profile is permitted. Approx. 13 m of pipeline with a nominal diameter of 50 mm were laid between a feed to a pump and a control valve on a test bench.
- the devices used are a pump from KSB, type Etanorm 32-160 with frequency converter, as well as a control valve from SAMSON, type 3241 with pneumatic drive and positioner.
- KSB type Etanorm 32-160 with frequency converter
- SAMSON type 3241 with pneumatic drive and positioner.
- a designed regulator was tested.
- the behavior of a consumer was simulated by a second fitting as an actuator of the above type. This allowed investigations on different models of the line.
- the test bench had the following characteristics:
- FIG. 2 shows a state space model of the installation extended by the dead times. This applies both in practice and in a test bench. Due to the signal processing in the control and measuring devices, dead times occur, which can not be neglected in comparison to a process dynamics. Also with a flow sensor used, for example, an inductive flow sensor, dead times must be considered.
- FIG. 3 shows a coupled controlled system.
- An output y> j is controlled by a plurality of manipulated variables Uj.
- a decoupling controller ideally consists of a path inverse coupling between a reference variable w, and a manipulated variable Uj. In the regulated overall system, therefore, each output v, by the action of the controller depends only on the reference variable Wj.
- the reference variables can be selected independently of each other.
- FIG. 3 shows the controller structure in the case of two inputs and outputs. The coupling in the system can not be derived directly from the state space representation, since a manipulated variable u usually only acts on one of the higher derivatives of the output y.
- Figure 4 shows a Smith predictor, a control element introduced in 1959 for frequency domain linear systems and since then present in various applications and modifications.
- the basic structure of the Smith predictor consists of a model, which is connected in parallel to the track. This makes it possible to return the calculated controlled variable before it can be measured.
- a state controller for linearizing the I / O behavior is designed for a deadtime-free SISO system.
- the state variables required for control are determined by a dead time-free model of the open path, in which the controller structure used is shown.
- a comparison of the predicted and the measured output is dispensed with here.
- Figure 6 shows the structure of the extended Smith predictor. This is a modification of a feedback in the outer loop is made. In contrast to the classic Smith predictor, however, it is not the output quantity that is calculated, but the difference between the measured and the calculated output. The dead time of the two real outputs is "synchronized" with those at the model outputs.
- the advantage of this structure is that with a suitable choice of the inner regulator circuit compensation of disturbances is possible.
- Fig. 7 shows measurement results with stepped change of the volume flow setpoint Q as n and a constant target value of the pressure pi, so n.
- the control and command variables have been shown and at the bottom of the manipulated variables and the loading thereof einpoundten state variables the actuators.
- the dynamic behavior of the controlled variables corresponds to the specifications. Only with very large jumps are small deviations from the nominal behavior in p ⁇ recognizable.
- Fig. 9 shows the reaction of the control circuit to a stroke change of the second valve, which simulates the influence of the consumer.
- This stroke change is shown in the diagram of the control valve as an additional measurement curve. Closing the valve causes a reduction of the volume flow as well as an increase of the pressure p ⁇ due to the increased resistance.
- the controller reacts by adjusting the manipulated variables until the disturbance is fully compensated. This is consistent with expectations regarding the integrating behavior of the Smith predictor.
