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 matri...

the control of fluidized-bed operations processes is still one of the major areas of research due to the complexity of the process and the inherent nonlinearity and varying dynamics involved in its operation. there are varieties of problems in chemical engineering that can be formulated as nonlinear programming (nlps). the quality of the developed solution significantly affects the performance ...
