Design of an Adaptive Integral Sliding Mode Controller for Position Control of Electronic Throttle Valve

Abstract

This study examines the effectiveness of an adaptive integral sliding mode controller (AISMC) for adjusting an electronic throttle valve's (ETV) angular position. An electronic throttle is a DC motor-driven valve that controls the flow of air into the engine in modern cars. Due to the nonlinear dynamical properties of electronic throttle systems, they are challenging to control using the conventional PID control technique. In the present investigation, an adaptive integral sliding mode control approach is recommended for controlling the ETV. First, the dynamical model of the electronic throttle is utilized to create an integral sliding mode controller (ISMC). The switching control term and the equivalent control term makes up the ISMC. The permissible minimum switching control term's gain is determined using the adaptive sliding mode control. The controller's chattering is reduced as a result. A computer simulation of the suggested control technique is then conducted, and the simulation results validate that the suggested control method has a sufficient degree of control performance. Regarding the transient features of the system, an analysis has been carried out to compare the effectiveness of the AISMC with alternative controllers. The MATLAB package's environment has been employed to implement the simulation.
