Different Active Disturbance Rejection Controllers Based on the Same Order GPI Observer
نویسندگان
چکیده
As the higher order or generalized extended state observer (ESO), proportional-integral (GPI) (GPIO) haves been proposed to enhance active disturbance rejection (ADR) control (ADRC) system's ability. However, different ADR controllers can be deduced based on same GPIO, resulting in dynamic performances. In this article, ten fourth GPIO are present. reveal relationship between these and conventional third ESO, six third-order-ESO-based present compared with fourth-order-ESO-based controllers. To ease comparison ADRC systems, a common expression is built for A novel frequency-domain analysis method also introduced how feedback law affects closed-loop performance. The effectiveness of verified test bench dSPACE DS1103.

On the Design of Discrete-time Fixed-order Controllers for Persistent Disturbance Rejection
Abstract: The focal point of this paper is the design of fixed-order controllers for persistent disturbance rejection. It is shown that optimal controller design can, in this case, be formulated as a generalized eigenvalue problems. The results in this paper rely on an extension of the concepts of equalized performance and superstability to the case of multiinput/multi-output systems described ...
متن کاملPower Active Filter Control Based on a Resonant Disturbance Observer
Active filters are power electronics devices used to eliminate harmonics from the distribution network. This article presents an active disturbance rejection control scheme for active filters. The controller is based on a linear disturbance observer combined with a disturbance rejection scheme. The parameter tuning is based on a combined pole placement and an optimal estimation based on Kalman-...
متن کاملExperimental Evaluation of Disturbance Observer-based Vibration Suppression and Disturbance Rejection Control in Torsional System
Abstract. In the resonance ratio control, the estimation speed of the disturbance observer should have been much faster than the resonance frequency of the controlled system. However, too fast disturbance observer causes implementation problem. In this paper, we give the optimal speed of the disturbance estimation and propose a novel technique, slow resonance ratio control, which enables us to ...
متن کاملDisturbance-observer-based Active Control of Transmission-induced Vibrations
This paper presents an alternative approach for active vibration control for systems with periodic disturbances of time-varying fundamental frequency. The motivation for this approach is active control of engine-induced vibration in automotive vehicles, where the fundamental frequency, i.e., engine firing frequency, goes from approximately 7 Hz at idle (840 rpm) to approximately 50 Hz (6000 rpm...
متن کاملVehicle Anti-Skid Control by Means of Extended State Observer and Active Disturbance Rejection Controller
When the driving road surface condition suddenly changes from dry to wet, the driving wheels will slip due to much lower coefficient of friction, and thus cause the vehicle to skid. Unlike the popular anti-brake system which applies differential braking to wheels, the presented ant-skid Control properly distributes torques to wheels without braking. In comparison with many recently developed an...
