During the realization of a control algorithm for the practical motor driver system, simulation is an important procedure before the algorithm is implanted into the DSP chip. In most circumstances, the simulation is done before the algorithm is realized, which is simulated under the condition of continuous control system. However, the simulation neglects the effect of the discrete system caused by...
In the high-speed permanent magnet synchronous motor(HS-PMSM) driver system, the current sampling is not accurate enough to support the calculation of complicated algorithm (vector control, direct torque control, etc.) since the current varies significantly in a single pulse-width modulation (PWM) period because of the small parameter of the HS-PMSM due to the high speed design. In this article a...
The control system simulation model is built based on the control system and hardware platform, which can reveal the situation of the actual system. However, it couldn't calculate the motor loss. The finite element simulation can analyze the loss in the all part of the motor, which usually use the ideally current source, neglecting the current harmonic caused by the control system performance, which...
