Emulator for an Actuator

The aim of this project is to develop an emulator that is the physical link between the simulation of an actuator running on the dSpace-HIL-System (Hardware in the Loop-System) and the real controlbox for the actuator. In association with this simulation model the emulator replaces a real actuator and its positioning sensors. This project deals with the development and the construction of a controllable voltage source in order to emulate the armature circuit of the actuator. This electronic source and load consists of two pulswidthmodulation amplifiers working as buck converters, which emulate the induced armature voltage. The armature resistance and inductance are implemented by physical parts. Furthermore, the position signals generated by the dSpace-HIL-System are being electrically isolated and used for emulating the position sensor signals. An upgrade for three phases is under construction in order to emulate three-phase alternating current motors. Another part of the project deals with the parameter estimation and the modelling of the simulation modules that are implemented on the HILL-System. The models of the motor, the load and of peripheral systems (as the incremental encoder) are implemented in matlab / simulink.
