Design and Testing of Hardware In the Loop Test Bench for Permanent Magnet Synchronous Motors controlled with Field Oriented Control Technique

This Master Thesis is the resoult of an internship in Teoresi SpA that provides the Hardware and the Software used to build an Hardware In the Loop (HIL) Test Bench for Permanet Magent Synchronous Motors (PMSMs). The aim of this work is the design and the testing of the HIL Test Bench. In the Test Bench the HIL 602+ Device by Typhoon HIL is used to real-time simulate the physical behavior of the electric machine. The real-time linux operating system is used to run the Field Oriented Control (FOC) algorithm and is operated from Labview. Both Typhoon and Labview software have been used to create an user-friendly Human-Machine-Interface (HMI) to run and monitoring in real-time the system simulation. Particular attention has been paid in the application of the field-oriented technique including the possivility to achive field-weakening conditions. An other important aim has been the testing of the performace needed by the system in terms of scan-time and how they can be maches form the device perfomances. To better understand the logic flux that has been followed here is reported a short list of the principals step of the all development: •??Hardware in the loop technique in servomechanism applications; •??Permanent magnet synchronous motor working principals; •??Field-Oriented control strategy for interior PMSM; •??Design of the system in Simulink; •??Export, manipulation and validation of the C-code control algorithm; •??Virtual and real-time simulation of the open test bench; •??Loop-closing with external real-time OS; •??Closed-loop Simulation; •??Conclusions and future developments.
