MPC Method with Input Voltage Observation for an Indirect Matrix Converter
摘要
Abstract
A novel model predictive control(MPC)method with input voltage observation was proposed for an induction motor drive system fed by indirect matrix converter(IMC). In this method,model predictive control theory was introduced in this system for good performances of the drive system and power grid requirements,and the problems that plenty of sampling for the hardware,the high cost of complex sampling circuit and the long time delay in the traditional MPC theory were solved. Specifically,an input voltage observer was designed based on the model of input filter. Moreover,the direct coupling between input reactive power prediction and input voltage was released. Simulation results show that the input/output currents of IMC are sinusoidal,and the induction motor can operate with a good tracking of torque and speed to their references quickly with a small overshoot. Those prove that a good static/dynamic performance of induction motor and the input/output sinusoidal currents are achieved. Meanwhile,three sampling hardware circuits are decreased. Finally,AD sampling circuit,digital filtering and processing delay are simplified.关键词
