Active Disturbance Rejection Control for Air-Breathing Hypersonic Vehicles Based on Prescribed Performance Function

Abstract

Aiming at the longitudinal motion model of the air-breathing hypersonic vehicles (AHVs) with parameter uncertainties, a new prescribed performance-based active disturbance rejection control (PP-ADRC) method was proposed. First, the AHV model was divided into a velocity subsystem and altitude system. To guarantee the reliability of the control law, the design process was based on the nonaffine form of the AHV model. Unlike the traditional prescribed performance control (PPC), which requires accurate initial tracking errors, by designing a new performance function that does not depend on the initial tracking error and can ensure the small overshoot convergence of the tracking error, the error convergence process can meet the desired dynamic and steady-state performance. Moreover, the designed controller combined with an active disturbance rejection control (ADRC) and extended state observer (ESO) further enhanced the disturbance rejection capability and robustness of the method. To avoid the differential expansion problem and effectively filter out the effects of input noise in the differential signals, a new tracking differentiator was proposed. Finally, the effectiveness of the proposed method was verified by comparative simulations.

MLP-Based Neural Guaranteed Performance Control for MEMS Gyroscope With Logarithmic Quantizer

“…To further improve the tracking performance in both transient and steady-state phases and remove the design conservatism universally existing in previous control methods for MEMS gyroscope, which can only ensure the closed-loop stability with UUB, prescribed performance control (PPC) proposed in [13]- [15] is an efficient strategy. Nowadays, PPC has been commonly used in uncertain nonlinear systems such as air-breathing hypersonic vehicle (AHV) [16], [17] and [35], robotic manipulator [13] and underwater vehicles [18]. With the aid of a proper equivalent error transformation function, PPC can assure the tracking error within predetermined boundaries, such that the prescribed performance can be realized without the tedious tuning of design parameters.…”

A Novel Linear Active Disturbance Rejection Control Design for Air-Breathing Supersonic Vehicle Attitude System with Prescribed Performance

“…As a derivative of hypersonic technique, air-breathing supersonic vehicle (ASV) is a new type of aircraft with large airspace, super flight velocity, long range, and high precision compared with the traditional aircraft [3], and flight guidance-control design is a key technology in the ASV system. However, as the special structure and changeable flight conditions, the vehicle dynamics are peculiar including the fast time varying, nonlinearity, uncertainty, and multiple disturbances [4], which lead to more difficulties and complexities in the control design and analysis. In addition, the ASV usually attacks the target at a supersonic velocity such that the flight states are changed rapidly which imposes a higher requirement for the transient characteristic of the control system [5].…”

“…Recently, a newly emerging control method called the prescribed performance control (PPC) for the nonlinear system was firstly proposed by Na et al [32], where the tracking error can converge to an arbitrarily predefined small set and the convergence rate and maximum overshoot can be delimited less than a prespecified constant. Owing to the significant advantages in improving the control performance, the PPC is introduced to the vehicle suspension system [33], manipulator system [34], servo mechanisms [35,36], unmanned aerial vehicle [37], spacecraft [38][39][40], etc., and several new ideas of the PPC design are emerged; [41] proposes a new error transformation method and the performance function so that the limitation of PPC on the known initial error can be relaxed. [42] investigates a new PPC methodology for the longitudinal dynamic model of an air-breathing hypersonic vehicle via neural approximation that the satisfactory transient performance with small overshoot can be achieved.…”

Practical Energy Dissipation Control of Near Space Glider on Independent Longitudinal Plane

“…An effective and weak model-dependent control strategy, which has a similar framework of the PID controller, is desired to regulate the attitude in reality. Recently, active disturbance rejection control (ADRC) [27,28], as an extension of traditional PID controller, has been widely used in industrial applications [29][30][31][32][33][34][35][36][37][38], and flight control is possibly the most active arena of ADRC [15,[38][39][40][41][42]. In the design, the ADRC only needs an open-loop control gain, which can be obtained relatively accurately than other characteristic parameters and can significantly reduce difficulty of modelling.…”
