Disturbance-Observer-Based LQR Tracking Control for Electro-Optical System

To improve the dynamic property and disturbance suppression ability of an electro-optical tracking system, this paper presents a disturbance-observer-based LQR control method. The robust controller is composed three parts: one controller, reference model other compensatory designed with output observer. uncertainty disturbances are considered in design. By Lyapunov stability theory linear matrix inequality (LMI) technique, sufficient conditions for observer gain system given. Simulation experimental results show that proposed method not only improved but also such as rise time, settling time overshoot. Specially, compared methods paper, accuracy about two to times higher. presented has important value field applications. But, development applications, cannot meet actual requirements system. next step will consider variety practical requirements, saturation problem target strong maneuverability, further optimize
