Experimental Investigation of Active Disturbance Rejection Control for Vehicle Suspension Design
نویسندگان
چکیده
This paper investigates the vibration attenuation problem of a vehicle suspension test rig, aiming at stabilizing its attitude. In the presence of nonlinear and unknown system dynamics, an accurate mathematical model of the test rig is not available. Active disturbance rejection control is employed to design a controller. An extended state observer is established to estimate the total disturbance which will be compensated in the controller design. The method will be very useful in industrial applications of active vehicle suspension because of its good robustness and easy implementation. Experimental results under different road profiles are used to validate the merits of the proposed control method. Key–Words: Active control, disturbance rejection, nonlinear dynamics, vehicle suspension

Voltage Control of Three Phase Inverters by Using Active Disturbance Rejection Control
Control of three phase inverters has been an important issue in recent years. This paper proposes active disturbance rejection control (ADRC) scheme for controlling three phase inverters. The main advantage of ADRC that motivated us for using this controller for inverter is that it is model independent. This controller is used in a double loop structure including an inner current loop and oute...
متن کاملH∞ gain-scheduled controller design for rejection of time-varying disturbances with application to an active suspension system
A new method for H-infinity gain-scheduled controller design by convex optimization is proposed that uses only frequency-domain data. The method is based on loop shaping in the Nyquist diagram with constraints on the weighted infinitynorm of closed-loop transfer functions. This method is applied to an active suspension system for adaptive rejection of multiple narrow-band disturbances. First, i...

متن کاملDesign of a Constrained Nonlinear Controller using Firefly Algorithm for Active Suspension System
Active vehicle suspension system is designed to increase the ride comfort and road holding of vehicles. Due to limitations in the external force produced by actuator, the design problem encounters the constraint on the control input. In this paper, a novel nonlinear controller with the input constraint is designed for the active suspension system. In the proposed method, at first, a constrained...
