description

Master's thesis Renewable Energy ENE500 - University of Agder 2018 The purpose of this research is to design a PSIM based controller for an inverter-fed Permanent Magnet Synchronous Motor (PMSM). The dimensioning and assembly of the controller are presented. The control algorithm used for the PMSM is Field Oriented Control (FOC). The report includes the theory of the control algorithm and its design. A PSIM based model is designed with the dimensioned components to analyse the behaviour of the controller. The model gives the opportunity of tuning the controller and verifying it with simulations. The model is then converted to be SimCoder compatible, enabling the simulation to be generated into a code. A Digital Signal Processing (DSP) development board is provided by Powersim Inc. The generated code is imported to the DSP, enabling it to run the controller. Similar behaviour is observed when comparing the test results with the simulations. When simulating the controller with the PMSM, all reference speeds are reached with a maximum deviation of 0:42%. Using PSIM proved to be an intuitive and educational way of designing the motor controller.
