This study proposes a design of an inner control loop for the load torque control of an electric load simulator (ELS), which is specifically designed to simulate load torque (i.e., load) for mechanical equipment. By mainly drawing on linear active disturbance rejection control, a mechatronic model-based inner loop controller of ELS is designed using measured torque to reduce the complexity of the estimator. A phase-locked loop observer is introduced to suppress the negative effects of the measurement error, thereby resulting in good performance for surplus torque suppression and the dynamic behavior of the control system. Simulations and experiments on a prototype machine are performed to verify the effectiveness of the proposed control method.

带转矩补偿的电力负载模拟器线性自抗扰控制

本研究提出了一种用于电动负载模拟器 (ELS) 的负载扭矩控制的内部控制回路设计，该设计专门用于模拟机械设备的负载扭矩（即负载）。主要借鉴线性自抗扰控制，设计了一种基于机电一体化模型的ELS内环控制器，利用测量转矩降低了估计器的复杂度。引入锁相环观测器来抑制测量误差的负面影响，从而在剩余转矩抑制和控制系统的动态行为方面具有良好的性能。在原型机上进行仿真和实验以验证所提出的控制方法的有效性。
