Tracking-Differentiator-Based Sliding-Mode Control for Tracking Control

Wenfei Li, Boyuan Li, Wei Hua et al. · 2023

Tracking control has attracted significant attention because of its close link with industrial applications. Tracking control requires that a control algorithm can ensure that an actuator follows control commands, with a fast response anti-disturbance abilities and small chattering. A tracking-differentiator-based sliding-mode control approach for tracking control is proposed in this paper. A tracking differentiator has the ability to obtain the desired signal's differential signal, even when there is noise in the desired signal. A differential signal is often required in the design of sliding-mode controllers. When tracking differentiator is applied to a sliding-mode controller, the chattering of the control commands (caused by noise disturbance) can be reduced while the fast response of the sliding-mode controller can be maintained. The simulation results show that the proposed controller is effective.

Path Tracking Control

qiuyan ge · Mendeley Data · 2025

This dataset contains simulation data of intelligent electric vehicles (IEVs) during path tracking tests, covering three typical operating conditions: straight-line path, double lane-change maneuver, and double sinusoidal trajectory. The data supports the verification and analysis of the proposed path tracking control algorithm, consistent with the simulation scenarios reported in the associated research article.

Tracking control for networked control systems

Wouw, N Nathan van de, Naghshtabrizi, P, Cloosterman, MBG Marieke et al. · Munich Personal RePEc Archive (Ludwig Maximilian University of Munich) · 2007

A solution to the approximate tracking problem for networked control systems (NCSs) with uncertain, time-varying sampling intervals and network delays is presented. The uncertain, time-varying sampling and delays cause inexact feedforward, which induces a perturbation on the tracking error dynamics. Two alternative modeling approaches are used: a discrete-time model and a model in terms of delay impulsive differential equations. Sufficient conditions for the input-to-state stability (ISS) of the tracking error dynamics with respect to this perturbation are given. These ISS results provide bounds on the steady-state tracking error as a function of the plant properties, the controller parameters, and the network properties. The results are illustrated on a mechanical motion control example.

Tracking Control System with Equivalent Perfect Tracking Control for Optical Disks

Tokoku Ogata, Naohide Sakimura, Tatsuya Nakazaki et al. · IEEJ Transactions on Industry Applications · 2012

An optical disk drive system must realize high-precision control. For this propose, a tracking control system, composed of a high gain servo controller (HGSC) and perfect tracking control (PTC), has been proposed. The conventional tracking control system adequately suppresses the tracking error caused by track eccentricity. However, the conventional system is complicated. The PTC system has a speed-up limitation in the optical disk tracking control system. Hence, this paper proposes a new high-speed and high-precision tracking control system that uses equivalent perfect tracking control (E-PTC). The proposed system realizes simple and quick execution in a digital signal processor for a software servo system. Our experimental results confirm that the proposed system effectively suppresses the tracking error at a DVD+R disk rotation speed of 7200rpm.

Acceleration assisted tracking control

Jager, AG Bram de · TU/e Research Portal (Eindhoven University of Technology) · 1994

This paper discusses the use of acceleration measurements to improve the performance and robustness of controllers for mechanical systems. To use acceleration signals there are at least two approaches: direct use in a feedback loop to improve the tracking error, and indirect use by an observer to improve the estimates of position and speed. Several proposals for the use of the acceleration in a feedback loop, resulting in slightly different controllers, are discussed. The design of the controllers for the experimental system, a flexible multiple degrees-of-freedom XY-table, uses a simplified two degrees-of-freedom model. The observer is of the predictive type to compensate for the time delay in the implementation, and its design is based in part on Kalman filter theory. Simulations and experiments show that both acceleration feedback and an acceleration assisted observer can improve the performance of the control system, but the robustness does not change significantly. A combination of both approaches did not give any improvement in the experiments, but some in the simulations. Disturbances in the acceleration signal (especially motor torque ripple), phase lag introduced by the signal processing equipment, time delay caused by the sampled data implementation of the controller and observer, and the non-colocated position and acceleration sensors are believed to be limitations for the usefulness of the acceleration signal. A performance improvement up to a factor of 1.5 was possible in the author's application, so to consider the use of acceleration measurements in tracking control is recommended.

Positioning And Tracking Control

Of An Table, Jian Wang, Hendrik Van Brussel et al. · 2003

In this paper, de-coupled discrete-time sliding-mode tracking controllers are designed for an x-y sliding table driven directly by linear motors. The controllers are designed using an integrated reaching law method, based on a simplified model of the current control loop of these motors. To achieve high bandwidth tracking performance, a feedforward controller is added. Although the sliding table is operating in the presence of friction, no friction compensation is applied. Experimental results are presented.

Robust Path Tracking Control

2021

This chapter begins with the model predictive control method due to its widespread use in automotive control applications and increasing use in path-tracking control. It presents the robust gain-scheduling controller design method, which is applied to automated vehicle lateral control. The integration of the road friction coefficient estimation module greatly enhances the safety of autonomous driving under adverse road conditions. Vehicle stability control is used in series production vehicles to deal with the danger of losing vehicle control or stability in versatile cases, such as over-reacted steering maneuver at high speed, driving on slippery icy road in winter, or being suddenly subjected to strong cross-wind. The chapter also presents and uses different strategies to determine the amount of extra yaw moment that is required, followed by differential braking distribution and simulation results.
