@conference { , title = {The first stage studies of U-state space control system design}, abstract = {In this study, a basic idea of U-state feedback control system design method is proposed based on U-model principle. Compared with U-model based nonlinear polynomial systems, the U-state space design is to determine the desired state variable equation xd(t), therefore to find the controller output u(t-1). The desired state equation can be designed/specified and transformed into the U-state space expression easily. The controller output can be obtained from resolving the equation. The desired state variables are updated by the corresponding state variables x(t). Assume that the state variables are measurable or obtained by a proper observer in this study. In case studies, two nonlinear discrete time state space models are selected to test the proposed approach. Computational experiments, that is, simulation studies, are used to demonstrate the procedure effectiveness.}, conference = {2015 34th Chinese Control Conference (CCC)}, pages = {946-951}, publicationstatus = {Unpublished}, url = {https://uwe-repository.worktribe.com/output/830813}, keyword = {Engineering Modelling and Simulation Research Group, control system synthesis, discrete time systems, nonlinear control systems, observers, polynomials, state feedback, state-space methods, U-model based nonlinear polynomial systems, U-model principle, U-state feedback control system design method, U-state }, year = {2015}, author = {Liu, Xin and Zhu, Quanmin and Narayan, Pritesh Praneet and Yang, Ye} }
