导引头稳定平台离散时间预设性能控制
A Discrete Time Prescribed Performance Control of Seeker's Stability Platform
摘要
Abstract
Aimed at the problems that existing discrete-time prescribed performance control(PPC)meth-odology is high in dependence on sliding mode reaching laws and obvious in chattering defects,a new dis-crete time PPC approach is proposed for a seeker's stability platform by constructing a new design frame-work without using sliding mode control.Firstly,the discrete time performance functions are developed to impose envelope constraints on tracking errors.And then,a discrete time transformed error is defined to construct a novel feedback function.Furthermore,discrete time PPC protocols are explored to stabilize the newly developed feedback function instead of the transformed error,guaranteeing not only all the tracking errors with desired prescribed performance,and remedying the defects of control chattering caused by the dependence of control algorithms on sliding mode reaching laws.Finally,by comparing the simulation re-sults and verifying,the method is valid and superior.关键词
