摘　　要：高速永磁同步发电机(HSPMSG)系统采用传统PI控制,负载突变时存在输出电压波动大、响应速度慢及抗扰性能差等问题,提出一种基于自适应超螺旋算法(STW)的高速永磁同步发电机稳压控制策略。在建立含控制延时交叉耦合项电流环控制模型的基础上,设计基于超螺旋算法的非线性电压控制律。同时,为抑制系统抖振,提出采用连续函数替换符号函数设计电压控制器。此外,针对扰动边界不确定与控制参数矛盾的问题,提出一种改进型自适应超螺旋算法(ASTW),并对稳定性进行了深入分析和理论证明。最后,搭建了仿真模型和实验平台,仿真和实验表明该控制策略可抑制系统抖振、减小电压波动,提高系统的动态响应速度和抗负载扰动的能力。In order to solve the problems of large output voltage fluctuation,slow response speed and poor anti-interference performance of high-speed permanent magnet synchronous generator(HSPMSG)system under traditional PI control,a voltage stabilizing control strategy based on adaptive super-twisting algo-rithm(STW)was proposed.Based on the current loop control model with control delay and cross cou-pling term,a nonlinear voltage control law based on super-twisting algorithm was designed.At the same time,in order to suppress the chattering of the system,the continuous function was proposed to replace the symbolic function to improve the voltage controller.Aiming at the contradiction between disturbance boundary uncertainty and control parameters,an improved adaptive super-twisting algorithm(ASTW)was proposed,and its stability is deeply analyzed and proved theoretically.Finally,the simulation model and experimental platform were built.The simulation and experiments show that the control strategy can sup-press the system chattering,reduce the voltage fluctuation,improve the dynamic response speed of the system and the ability to resist load disturbance.
