Abstract: For induction motor vector control system, a predictive functional controller used as velocity loop controller was proposed, and PI control was used as a current loop controller. Firstly, the parameters of the mathematical model for induction motor was established using the experimental method, then based on the principle of predictive functional control, speed regulator was designed. Secondly, This proposal was tested based on DSP TMS320LF2407 motion control system platform and compared with traditional PI control. Experimental results show that the predictive functional control method is simpler, faster and more robust than conventional PI control, and has practical value.
