A New Approach to Selecting Optimal Parameters for the Sliding Mode Algorithm on an Automotive Suspension System

چکیده
Stimuli from the road surface cause car vibrations. The suspension system ensures vehicle’s stability and smoothness when moving. In this research, author introduces use of active with a hydraulic actuator to improve comfort cars. Car oscillations are described based on quarter-dynamics model five state variables. Besides, nonlinear system’s SM (sliding mode) control algorithm is used system. algorithm’s parameters optimally selected using multiple loop algorithm. allows values vary within predefined limit provides an optimal parameter vibration conditions. This new point in paper compared previous studies. output simulation problem includes displacements accelerations both sprung unsprung masses. addition, change dynamics force at wheel also considered evaluating interaction between surface. According paper’s results, vehicle body’s acceleration displacement strongly reduced algorithm, cars only traditional suspension. not significant As result, car’s has been improved while lost. phenomenon “chattering” still occurs some cases; however, its effect negligible.

This study develops a fuzzy sliding mode controller (FSMC) based on a variable boundary layer. A fuzzy inference mechanism is used to on-line tune the thickness of the boundary layers of the controller. Minimum rule base has been used for the fuzzy inference system which results in low calculation effort. The aim of this paper is to design a controller which will eliminate the chattering of FSM...

One of the most important applications of multi-objective optimization is adjusting parameters ofpractical engineering problems in order to produce a more desirable outcome. In this paper, the decoupled sliding mode control technique (DSMC) is employed to stabilize an inverted pendulum which is a classic example of inherently unstable systems. Furthermore, a new Multi-Objective Particle Swarm O...
