对于具有不确定性的多输入多输出非线性系统,仅用I/O线性化设计方法不能获得好的控制结果。为此,设计了自适应模糊控制器,把I/O线性化方法和自适应模糊控制相结合,构成混合控制器。并将此控制器引入到卫星大角度机动控制系统中,以补偿由系统的不确定性所造成的跟踪误差,从而增强I/O线性化控制器的鲁棒性,最终实现零误差跟踪。
For uncertain MIMO-based systems, good control results can not be achieved using only the I / O linearization design method. To this end, an adaptive fuzzy controller is designed to combine the I / O linearization method and the adaptive fuzzy control to form a hybrid controller. The controller is introduced into the satellite large-angle maneuvering control system to compensate for the tracking error caused by the system uncertainty, which enhances the robustness of the I / O linearization controller and finally achieves zero-error tracking.
