题目: New Results on Control of a Class of Nonminimum-Phase Nonlinear Systems by Output Feedback

报告人: Wei Lin教授, Case Western Reserve University, USA

摘要: This lecture will present some new results on global stabilization by output feedback for nonminimum-phase nonlinear systems of a cascade configuration that consists of a driven system (inverse dynamics) and a driving system. Although the zero dynamics may be unstable, there exists an output feedback control law, globally stabilizing the nonlinear system, if both the driven and driving systems have a triangular form and satisfy a global Lipschitz-like condition, and the inverse dynamics is input-to-state stabilizable. A controller design algorithm, examples and simulation results are presented to demonstrate the control strategy and its effectiveness. Discussion will be given on control of nonminimum-phase nonlinear systems, a challenging and important open research topic.
