【摘要】 在模型参考自适应控制中,以往消除扰动的方法是将系统输出和干扰同时反馈来提高系统性能和消除干扰,两者只能折中实现。针对此问题,结合自适应逆控制理论和超稳定理论,提出了一种克服随机扰动的离散MRAC设计方法。本方法引入自适应逆模型来消除系统扰动,将对象性能和扰动控制分开单独进行处理,可分别提高各自的性能。仿真实验证实了方法的可行性。更多还原

【Abstract】 In model reference adaptive control (MRAC), usually the object function control and disturbance control are mixed together to carry on the feedback control, thus the control must be exerted on both the function and the disturbance. On the basis of the adaptive inverse control and the hyperstable theory, a method of designing discrete MRAC, which overcomes random disturbance, is proposed. The method separates to control exportation and disturbance by inducing the adaptive inverse model, it can raise functions respectively as soon as possible. Simulation results show that the feasibleness of the proposed method.更多还原
