Research On Tornambe Control Technology Of Asynchronous Motor Speed Control System

For high-performance speed control of the motor system,the robustness of the controller is one of the important performance indicators as a measure of its merits.The traditional PID controller cannot fully meet the control requirements,under this condition,Antonio Tornmabe proposed a novel but simple structure of the control method to design a robust controller.Aiming at the hypothesis condition outputs and its derivatives are known ahead of time is difficult to meet in the practical engineering application,high gain observer for state estimation is special addition used.This improvement is very important to the engineering application of the traditional Tornambe controller.On the basis of this,the Monte Carlo simulation experiment of modified Tornambe control under MATLAB / SIMULINK is carried out,and the controller performance meets the design requirements.Based on the simulation of the SVPWM strategy,the Tornambe controller is applied to the asynchronous motor speed control system.Optimization of the PI method,the traditional Tornambe controller(TC)and improved Tornambe controller(OTC)is used to control the speed of the motor system.The results show that,in the case of large changes in the parameters of the controlled object,the dynamic performance and robustness of TC control are significantly better than PI control.The dynamic performance and immunity performance of OTC and TC are similar,but OTC has a better performance in robustness and is more suitable for engineering applications.The OTC controller is applied to the asynchronous motor speed test platform and to be verified on the actual motor system.The result also shows that the control effect is superior to the traditional PI control system.
