## Matlab交流电机矢量控制仿真设计

Abstract: Vector control is an advanced control strategy which basicly developed by eletrical machine unified theory,electromechanical energy and coordinate transform theory.Becoming an improtant trend in Ac speed control with novelty and practicability characteristics.The paper expounded the basic theory and asynchronous machine of vector control was performanced under the dynamic mathematical models with different coordinate systems.The generation of algorithm and simulation realization was analyzed by SVPWM wave.According to the principle of asynchronous motor vector control and basing on the analysis of control plan, a total design scheme about asynchronous vector control was offered by indirect directional.The slip vector control system was established based on the vector control equations of slip.Using Matlab/Simulink to bulid and study the simulation model by magnetic flux loop vector control sysytem.The result shows that the method of simulation is rationality and validity,a new way is provided by design and debug the actual motor control system. 源`自*六)维[论*文'网www.lwfree.cn
