摘要
由于多余力矩严重影响了电动负载模拟器的加载性能,提出了一种复合控制方法对该问题进行研究。首先考虑承载对象运动带来的干扰,建立了系统的数学模型;然后,针对控制系统单独采用前馈补偿或自适应控制方法的局限性,进行了基于前馈控制和模型参考自适应控制的复合控制系统设计,并利用Lyapunov函数的方法构造了自适应控制器。最后的仿真结果表明,采用复合控制方法能够大幅度消除电动负载模拟器的多余力矩,验证了控制策略的可行性。
Since the loading performances of motor-driven load simulator are seriously influenced by the extra torque in the loading process,a composite control method is presented for solving the problem. Firstly,the model of load system is build by considering the interference impact of the steering gear. Then,to overcome the limitation of the feed-forward compensation or the adaptive control method separately used for the system,the composite control strategy using feed-forward control and model reference adaptive control is proposed to design the control system,and the adaptive controller is designed by means of constructing Lyapunov function. Finally,simulation results show that the composite control can substantially reduce the extra torque,and the correctness of the control method is validated.
