| Summary: | 碩士 === 國立東華大學 === 電機工程學系 === 102 === The objective of this thesis is to develop a V/f control with stabilizing feedback loop and current phase control on permanent magnet synchronous motors in order to achieve the purpose of sensorless control and energy improvements.
In the validation of the control structure, we first use Matlab/ Simulink to simulate and verify ideal. Then, we design a full drive system including the software and hardware with DSP28335 as the control center to implement the control strategy.
For the software part, we use DSP28335 to implement the control strategy including a Finite Impulse Response (FIR) filter design and a Space Vector Pulse Width Modulation (SVPWM) algorithm.
On the other hand, for the hardware part, we make a motor inverter, a three phase rectifier circuit, current sensing circuit, and a ADC interface circuit to drive a PMSM motor.
