Definitions
- the present invention relates to a method and a device for setting a digitally controlled Magnetspei- seêt.
- Particle accelerators require high-precision magnetic feeders. There is a fundamental desire to further increase the precision of existing equipment as well as that of new equipment. The current situation and the way to increase the quality of the existing power supply units are briefly described below:
- PID proportional integral derivative controller
- state controller linear / nonlinear control
- adaptive structure continuous-time / discrete-time control
- PID structures are used for regulations.
- PID controllers are generally robust, i. even with not quite optimal design (typically loads that do not behave as well as modeled) good results are obtained and the controlled systems are stable. Extended to include adaptive properties, anti-wind-up, etc., the behavior can be further improved. This is the proven control structure of today's devices.
- the invention is therefore based on the object of specifying a method and a device for controlling a magnetic power supply, with which the robustness of the control concept increased, the reaction times of the control concept further shortened and the precision of the control concept is further improved.
- a method for the regulation of a magnetic feed device which comprises the following steps: a) carrying out a basic structure of the control as a double-loop control with a voltage control loop for the magnet voltage and a current control loop for the magnetic current, the ⁇ in the control loops are preferably summarized in a controller; b) performing the voltage regulation loop as a state regulator, the state controller feedback parameters adaptively adapting, as needed, the behavior of a power converter, an output filter, and a load; c) modeling the behavior of the power converter, the Changfil ⁇ age and the load with an observer (Observer, Luenberger observer, Kalman filter) and tracking the observer in adaptation to the effective behavior of the power converter, the Aus ⁇ input filter and the load; and d) implementing the current control loop as an adaptive PI controller.
- a device for controlling a magnetic power supply comprising the following components: a) a basic structure of the control as a double-loop control with a voltage control loop for the magnet voltage and a current control loop for the magnetic current, the two rule ⁇ circuits are preferably summarized in a controller; b) the voltage control loop is implemented as a state controller, wherein the feedback parameters for the state controller are adaptively adaptable to the behavior of a power converter, an output filter and a load if necessary; c) an observer to model the behavior of the power converter, output filter and load, with the observer tracking the effective behavior of the power converter, output filter and load; and d) the current control loop is designed as an adaptive PI controller.
- this system model can achieve improved robustness over the known in the prior art regulator using the obser ⁇ ters (Observer).
- the course of the observer is continuously tracked as closely as possible to the behavior of the physical system.
- the system behavior can be time and work point dependent.
- an identification of the output filter and the load can be made for the calculation and adaptation of the control coefficients on the fully installed magnetic feeder.
- the basic function and its associated parameters can thus be determined cleanly.
- the identification can be carried out in a special operating mode in which parameters that are as realistic as possible to operation can be obtained. Alternatively, however, the identification can also be carried out continuously during operation.
- control structure can typically be realized in a time-discrete manner.
- Figure 1 is a schematic representation of a block diagram of a regulated according to the invention magnetic feeder.
- Figure 2 is a schematic representation of a block diagram for the
- An embodiment is implemented in a corrector power supply having the following configuration:
- the basic structure of the control is 'double-ended'.
- the two control loops can also be combined into one controller.
- the voltage control loop is executed as a state controller. If necessary, the feedback parameters are adaptively adapted to the behavior of the converter, the output filter and the load. Since the voltages at and currents in the output of the actuator and in the filter are noisy and have a large ripple, they can not simply be measured and used for the feedbacks of the state controller.
- the converter, the output filter and the load are therefore modeled with an observer (Observer, Luenberger observer, Kalman filter). The observer is tracked to the effective behavior of the circuit.
- the current control loop is implemented as an adaptive PI controller.
- an identification of the filter and the load is made on the completely installed device (that is to say with load). This identification is currently being made in a special mode of operation. Likewise, it would also be possible to carry out the identification continuously during operation.
- the necessary limits for the correct operation of the control and protection functions for the power converter for example, d / dt limitations where necessary) are provided.
- the final rule structure is realized time-discretely.
- control cycle In conventional controls, a meaningful control cycle is at most as fast as an AD converter cycle. For precise transducers, this cycle time is a very limiting magnitude. In the case of the use of the observer data selected here, the control cycle can be selected as fast as possible independently of the AD converter, as is still useful with regard to the controllability of the semiconductors.
- a numerical system image is calculated by means of multi-dimensional optimization.
- the controller coefficients are then determined from this.
- the measurement of the data is done with magnetic feeder and associated controller.
- the determination of the system image and the calculation of the control coefficients are currently still performed on a PC. Then the coefficients are loaded into the controller and the system runs autonomously. For this operation, the schematic block diagram according to FIG. 2 applies.
