Estimation-Free Prescribed Performance Control for Input-Constrained Waverider Vehicles
摘要
Abstract
In view of tracking control problem of input-constrained waverider vehicles,an estimation-free prescribed performance control scheme is proposed.Firstly,a new anti-saturation compensation system is designed to address the possible problem of actuator saturation.Then,the states of the compensation sys-tem are used to construct new prescribed performance transformed errors,and the controller is designed directly using the constructed new prescribed performance transformed errors based on the prescribed per-formance control and backstepping control methods.Then,a new prescribed performance transition error is constructed using the compensated system state,and low-complexity controllers without estimation are designed for the velocity subsystem and the altitude subsystem based on the method of prescribed perform-ance control and backstepping control.The superiority of this method is that it eliminates the need for state estimation and neural approximation,which significantly reduces the complexity and computation of the control.Based on Lyapunov stability theory,it was proved that all transformed errors and tracking er-rors of the system are ultimately uniformly bounded.Finally,the effectiveness of the provided method are validated via numerical simulation.关键词
