Design and Comparative Study of Advanced Adaptive Control Schemes for Position Control of Electronic Throttle Valve

Abstract

This paper investigates the performance of two different adaptive control schemes for controlling the angular position of an electronic throttle (ET) plate. The adaptive backstepping controller and adaptive sliding mode backstepping controller are the controllers under consideration. The control design based on these adaptive controllers is firstly addressed and the stability analysis of each controller has been presented and the convergence of both position and estimation errors for both controllers have been proved. A comparison study of the performance of both controllers has been conducted in terms of system transient characteristics and the behavior of their associated adaptive gain. The simulation has been implemented within the environment of the MATLAB package.

Control Allocation-Based Robust Tracking Control for Overactuated Surface Vessels Subject to Time-Varying Full-State Constraints

“…Furthermore, using Lemma 1, it is obvious from ( 27) that e o converges to zero in a finite time, and corresponding reaching time is T = T d + T f . Lastly, according to the definition of sliding variable (18), it is concluded that disturbance estimation (26) can converge to its true value f . Remark 2.…”

Stability Analysis and Chaos Control of Electronic Throttle Dynamical System

“…We introduced the control signal represented by equation (17) to equations (19a)− (19c) to synchronize equations ( 18) and (19). is yields the following coupled system:…”

“…Because electronic throttle valve systems feature many nonsmooth nonlinearities, the system is very hard to control [13][14][15]. Several studies have investigated nonlinear control for electronic throttle systems [16][17][18][19][20], which are typically depicted by a nonlinear dynamical system [13,17]. Modifying one of these parameters alters the dynamics that exhibit chaos motion, leading to instability of engine running.…”

Adaptive backstepping sliding mode control design for vibration suppression of earth-quaked building supported by magneto-rheological damper

“…The adaptive control technique is used to adapt the parameters of controller such as to cope with these uncertainties, disturbances or vibration such as to keep the controlled systems within stability margins. [33][34][35][36] One critical problem with building systems subjected to earthquakes is that their parameters such as spring and viscosity coefficients encounter evitable variations under earthquake vibration. Therefore, one solution to fix this problem is to propose an adaptive control.…”
