Definitions
- the present invention relates to a method for adjusting a pressure medium supply for at least one hydraulic actuator and a hydraulic system which comprises at least one hydraulic actuator.
- the hydraulic system comprises in particular a displacement unit with an adjustable displacement volume, which supplies the hydraulic actuator with a pressure medium, a variable speed drive that drives the displacement unit, and a control for adjusting the displacement volume of the displacement unit and the speed of the drive.
- the method provides that the actuator is supplied with a pressure medium by a displacement unit whose displacement volume is adjustable, the displacement unit is driven by a variable speed drive and a quantity of pressure medium to be supplied to the actuator is specified by a size profile.
- a cyclically repeating size profile is specified for the states to be assumed by the hydraulic actuator.
- a time-dependent path profile (or position profile) to be assumed by the hydraulic actuator is specified.
- a force profile can also be specified.
- the volume flow and/or the delivery pressure can be adjusted over time by adjusting the displacement volume of the adjustable displacement unit and/or the speed of the drive. Since the delivery system consisting of an adjustable displacement unit and a variable speed drive has two degrees of freedom that can be adjusted with a control system, it has proven to be problematic in practice to operate the hydraulic system optimally.
- DE 10 2013 006 137 A1 proposes that a model-based optimization problem be integrated into the control system for setting the speed setpoint and the setpoint for the displacement volume, for which purpose an objective function is specified for the process sequence.
- a model-based optimization problem also requires that other parameters of the system be incorporated in addition to the size profile.
- the object of the present invention is therefore to eliminate the disadvantages explained with reference to the prior art and in particular to provide a method for adjusting a pressure medium supply and a hydraulic system with which properties such as the energy consumption and/or the dynamic behavior of a hydraulic system can be improved in an alternative manner, wherein in particular the commissioning should also be simplified.
- the problem is solved in particular by setting a speed setpoint of the drive and/or a setpoint for the displacement volume of the displacement unit taking into account a knowledge-based decision system.
- a knowledge-based decision system Preferably, both the speed setpoint of the drive and the setpoint for the displacement volume are set taking into account the knowledge-based decision system.
- the knowledge-based decision system can be designed, for example, as fuzzy logic or as a neural network.
- control of the hydraulic system includes a knowledge-based decision system.
- the basic idea of the invention is that instead of a concrete optimization problem, an improvement of the system behavior (energy consumption, dynamic behavior) is achieved on the basis of a knowledge-based decision-making system (e.g. fuzzy logic, neural network).
- a knowledge-based decision-making system e.g. fuzzy logic, neural network.
- fuzzy logic input variables of the fuzzy logic are assigned to a set based on their degree of membership.
- operations fuzzy rules
- the membership functions and the fuzzy rules are based on expert knowledge, which in turn can be based on component knowledge, simulations, empirical values or experiments.
- a knowledge-based decision-making system when the specified size profile changes, it can optimize the speed of the drive and the displacement volume of the displacement unit, in particular so that less energy is consumed for a cycle or the dynamic behavior is improved during critical processes in the cycle.
- the cycle specified by the size profile can be divided by the knowledge-based decision system into various segments arranged one after the other in time, which differ from one another in particular by a change in at least one state variable of the size profile, with the knowledge-based decision system preferably optimizing the speed and the displacement volume for each segment of the cycle.
- the speed (or, if applicable, the different speeds of the multiple segments) and the displacement volume (or, if applicable, the different displacement volumes of the multiple segments) are changed taking into account the initial values of the knowledge-based decision system and further optimized for the next cycle taking into account the energy consumed in the cycle.
- a closed control loop is designed to adjust the displacement volume, so that the adjustment of the displacement volume takes place in a closed control loop.
- the displacement volume is changed according to the requirements of the size profile within a cycle by means of a closed control loop.
- the knowledge-based decision system is set up to provide a manipulated variable for setting the speed of the drive.
- a discrete output variable or a discrete set of output variables provided by the knowledge-based decision system is therefore used as a manipulated variable for setting the speed of the drive.
- a discrete output variable exists, for example, when the knowledge-based decision system specifies exactly one value for the speed of the drive during an entire cycle.
- a discrete set of output variables exists when the knowledge-based decision system specifies several, mutually different speed variables of a cycle for the drive. It can therefore be provided that the speed of the drive is set exclusively taking the knowledge-based decision system into account, while the displacement volume of the displacement unit is also set in a closed control loop, possibly without taking into account a specification by the knowledge-based decision system.
- the knowledge-based decision system is set up to provide a pilot control variable of the control variable for setting the displacement volume.
- a discrete output variable if the Displacement volume is constant over a cycle
- a discrete set of output variables if the displacement volume of the displacement unit changes over a cycle
- the displacement volume is also controlled solely taking the knowledge-based decision system into account. The correction value of the displacement volume provided by the knowledge-based decision system as a pilot control value is therefore used to further optimize energy consumption.
- the parameters of a cycle are fed to the knowledge-based decision system as an input variable.
- the speed set during a cycle or the speeds set during a cycle can be fed to the knowledge-based decision system as an input variable.
- the displacement volume set during a cycle or the various displacement volumes set during a cycle can be fed to the knowledge-based decision system.
- the process variables such as path, force can be fed to the knowledge-based decision system.
- the energy consumed during a cycle (for example the electrical energy supplied to the drive and possibly also to the displacement unit) is also fed.
- the discrete input variables can, for example, be assigned to a fuzzy set with a certain degree based on a membership function when using a fuzzy algorithm.
- the operations (fuzzy rules) of the fuzzy logic are set up in particular so that a value, possibly referred to as a reference value, is optimized for a cycle.
- the operations of the fuzzy logic are set up in particular so that the output variables can lead to an optimization of energy consumption and/or an improvement of the dynamic behavior of a cycle.
- both the allocation of the input variables to the fuzzy set and the fuzzy rules of the fuzzy logic are based on expert knowledge, which is derived in particular from component knowledge, simulations, empirical values and experiments. Fuzzy logic is sufficiently well known as such, so that the specific setup of fuzzy logic will not be discussed further at this point.
- the displacement unit is preferably operated as a motor or as a displacement pump.
- the displacement unit which has an adjustable displacement volume, can be designed as a radial piston or axial piston machine, for example.
- the variable speed drive is usually an electric motor.
- the figure shows a hydraulic system which comprises an actuator 1, a displacement unit 2 with an adjustable working volume and a variable speed drive 3 which drives the displacement unit 2.
- the amount of pressure medium to be delivered to the actuator 1 can be set by setting a speed setpoint of the drive 3 and by setting the displacement volume of the displacement unit 2.
- the hydraulic system also includes a control system.
- a closed control circuit 6 is provided, which includes a position measuring system for the actuator 1.
- the closed control circuit 6 also includes a controller 7, by means of which the displacement volume of the displacement unit 2 is set.
- the control system also includes a knowledge-based decision system 5, the output variables of which are passed on to a control system 8.
- the knowledge-based decision system 5 also receives the process parameters such as speed, displacement volume and energy consumption of the drive 3 as input variables.
- the knowledge-based decision system 5 is designed as a fuzzy logic/algorithm.
- the knowledge-based decision system 5 can be designed as a neural network.
- the hydraulic system is given a size profile 4 (for example a force profile and/or a position profile) which is to be cyclically traversed by the actuator 1.
- the size profile 4 is fed to both the controller 7 and the pilot control 8.
- the process variables recorded in an identification cycle are fed to the knowledge-based decision system 5, whereby these input variables are assigned to fuzzy sets 9 with a degree of their membership when the knowledge-based decision system is designed as fuzzy logic.
- An operation (fuzzy rules 10) is carried out on the basis of the fuzzy sets 9 determined in this way, from which discrete output variables 11 result.
- These output variables 11 are fed to the feedforward control 8, whereby the value for the speed of the drive 3 is fed to the drive 3 as a manipulated variable.
- the value for the change in the displacement volume is fed to the manipulated variable of the controller 7 for setting the displacement volume.
- the assignment of the input variables to the fuzzy sets 9 and the fuzzy rules 10 are set up on the basis of expert knowledge in such a way that the speed and/or the displacement volume for the next cycle can be optimized to ensure the lowest possible energy consumption and/or to improve the dynamic behavior during critical processes in the cycle.
