摘　　要：变转速泵控系统具有动力学阶数高、强非线性、参数时变等控制难点。建立了交流永磁同步电机驱动的变转速泵控马达系统的完整数学模型。在模型简化的基础上,引入串级系统的思想设计自抗扰控制器。通过PID控制和自抗扰控制的对比仿真研究,验证了自抗扰控制器的控制性能。仿真结果表明,自抗扰控制器能较好克服系统阶数降低的影响,不但在基本恒定负载下响应快、跟踪精度高,而且在突变力矩干扰下时,展现出较好抗干扰能力。Variable speed pump control system has many control difficulties,such as high dynamic order,strong nonlinearity,time-varying parameters and so on.In this paper,a complete mathematical model of variable speed pump controlled motor system driven by permanent magnet synchronous motor is established.On the basis of model simplification,the idea of cascade system is introduced to design ADRC.Through the comparative simulation of PID control and ADRC,the control performance of ADRC is verified.The simulation results show that the ADRC can overcome the influence of system order reduction;it not only has fast response and high tracking accuracy under basically constant load,but also shows good anti-interference ability under abrupt disturbance.
