U-model based LMI Robust Controller Design

摘要：

　　In this study,an LMI (Linear Matrix Inequality) based H∞ robust controller design approach is proposed to improve the performance of the designed U-pole placement control systems.Unlike the classical design procedures,the control-oriented U-model based nonlinear control systems cancel the nonlinearity of the nonlinear models.Therefore,the closed loop transfer function of U-pole placement control system can be regarded as a linear block.The solvability and sub-optimality of discrete-time H∞ Robust control are converted to find feasible solutions for LMIs.Once the internal parameters changed,the LMI based H∞ Controllers have a higher level of robustness compared with U-pole placement controllers.A nonlinear dynamic model is selected to test the performance of the LMI robust controller to demonstrate the proposed approach effective.
