摘要

本文研究了基于间接磁场定向控制(IFOC)方案的三相鼠笼式异步电动机(IM)速度控制。本文用滑模控制器(SMC)取代了传统IFOC的比例积分(PI)速度控制器，并对两者的性能进行了比较。仿真结果表明，采用PI控制器的IFOC方案在稳定状态下具有良好的性能，只要对其增益参数进行了适当的调整。在所提出的拓扑结构中，采用双曲正切函数的SMC作为开关函数，以减小抖振效应。仿真结果表明，基于SMC的IM驱动器在宽速度范围内具有较高的动态性能，并且对外部干扰和参数变化具有较强的鲁棒性。利用MATLAB/ SIMULINK软件进行了不同工况下的仿真实验，验证了控制器的有效性。

Robust Sliding Mode Control Strategy Applied to IFOC Induction Motor Drive

This work deals with the speed control of three phase squirrel cage induction motor (IM) based on Indirect Field Oriented Control (IFOC) scheme. The Proportional - Integral (PI) speed controller of conventional IFOC is replaced with Sliding Mode Controller (SMC) in this work and performance by both are compared. Simulation results show that the IFOC scheme with PI Controller presents good performance under steady state if its gain parameters are tuned perfectly for that operating condition. In the proposed topology, SMC with hyperbolic tangent function is used as switching function aiming a reduction in chattering effect. Simulation results shows that SMC based IM drives are capable of developing high dynamic performance in wide speed range applications and is robust to external disturbances and parametric variations. Simulation experiments under different operating conditions are carried out using MATLAB/ SIMULINK software to validate the effectiveness of the controller.
