非线性1/4车辆主动悬架系统的安全控制
Safety Control of Nonlinear 1/4 Vehicle Active Suspension Systems
摘要
Abstract
For the nonlinear 1/4 vehicle active suspension system,a control strategy with safety constraint is inves-tigated in this paper.How to choose the best performance control under the condition of ensuring safety is main challenge,and the under-actuation of the system also increases the difficulty of design.Firstly,a transformation is skillfully designed and the constraint condition of practical exponential stability is given.Then,considering both ride comfort and safety,a reasonable safety constraint function is provided,and the safety constraint condition is given by using control barrier function.Finally,a quadratic programming problem that coordinates performance and safety is formulated,and a closed-loop solution to this problem is provided.Simulation results validate the effective-ness of the proposed scheme.关键词
