Wiener-Typed Nonlinear Systems´ Output Feedback Control Algorithm Based on Dual-Mode Method

Wiener-typed nonlinear systems with hard input constraints are ubiquitous in industrial processes. However, owing to their complex structures, there are very few achievements on their control algorithm. Aimed at this problem, an improved dual-mode control algorithm is put forward. Firstly, the detailed procedure of this algorithm is proposed. Then, its feasibility, stability and convergence are analyzed by using the invariant set theory combined with LMI (linear matrix inequalities) technique . In contrast to traditional algorithms, this one has the capabilities of maximizing the size of the closed-loop stable region and decreasing the online computational burden. Finally, the proposed algorithm is performed by simulations with promising results
