High-performance of Frequency Conversion Regulating Speed System Based on the Theory of Robustness Internal Model

Starts with the robustness mechanism of internal model control(IMC),the performance of the internal model control is analyzed, it has the good performance of anti-disturb and robustness. Because the influence of machine time-varying parameter on the performance of vector control system and presents a new high-performance induction motor frequency conversion regulating speed internal model control system. The current regulator and speed regulator based on IMC are designed. It can effectively solve the problem of the weak performance of parameter robustness in vector control system. The theories and the experiments demonstrate the validity of this project.
