Research of Fuzzy Adaptative Vector Control of Asynchronous Motor Based on DSP

摘要：

The paper presents a dual closed-loop vector control system based on DSP for asynchronous motor which is a multi variables,nonlinear,strong coupling and timevarying system and is difficult to determine precise mathematical model because of changes in motor parameters and load fluctuations in factors. Speed controller uses a parameters self-adjusting fuzzy controller and flux observer uses an improved combining methods of voltage model and current model. simulation results illustrate that the system obtains satisfactory results in the dynamic response,antiinterference ability and robustness.
