摘　　要：为提高永磁同步电机(PMSM)调速系统的H_(∞)控制性能,本文首先建立PMSM的Takagi-Sugeno(T-S)模糊动态模型,然后构造了新的双边闭环性Lyapunov泛函,并运用自由权矩阵积分不等式得到该系统的渐近稳定性的充分条件。然后设计了H_(∞)跟踪控制策略,该控制策略具有良好的调速性能。最后,通过仿真验证了所提出控制策略的有效性。To improve the H_(∞)control performance of permanent magnet synchronous motor(PMSM)speed regulation system,this paper establishes a Takagi-Sugeno(T-S)fuzzy dynamic model firstly.Then,a new two-sided looped Lyapunov functional is constructed,and sufficient conditions for system asymptotic stability are obtained using the free-matrix-based integral inequality.Subsequently,this paper proposes a design for follow-up control strategy on solving the H_(∞)controller,and the control strategy has excellent speed regulation performance.Finally,the effectiveness of the proposed control strategy is verified through simulation.
