摘　　要：通过分析电动负载模拟器的基本结构和工作原理,建立数学模型并且分析了多余力矩产生的机理,提出一种重复控制和PID控制相结合的复合控制策略,利用重复控制改善系统的稳态特性,利用PID控制改善系统的动态特性。仿真结果表明,所采用的方控制方法能够有效地抑制多余力矩,提高了系统的稳态精度和动态性能。In this paper, through analyzing the basic structure and working principle of electric load simulators, the mathematical model of simulators is established and the mechanism of superfluous torque is analyzed. An integrated control strategy combing repetitive control and PID control is proposed in this paper. The repetitive control is used to improve the steady state characteristics of the system, and PID control is to improve the dynamic characteristics. The simulation results show that the control method is effective to restrain superfluous torque and improve steady precision and dynamic performance of the system.
