摘　　要：提出了多模型自适应变频调速系统的新型控制结构,解决常规自适应控制所无法解决的调速系统电机电阻存在的不确定性较大及电机电感的不确定性变化较快等难点问题。理论分析与仿真实验表明了方案的正确性与合理性。Applies multi - mode adaptive control theory to asynchronization motor variable - frequency modulation system to solve the bad parameter luenberger in vector control system. Under vector scheme, separately established rotate speed subsystem, flux subsystem mode and designed correspond velocity control multi - mode adaptive controller, proposed new control structure of multi - mode adaptive variable - frequency velocity modulation system. Theoretic analysis and simulation result indicate that the theory above - mentioned can solve some issues as uncertain motor resistance and uncertain motor inductance which tradition system can not be solved, the system possesses excellent dynamic and static performance.
