Discrete-time sliding mode control for MR vehicle suspension system

Fuzzy Sliding Mode Control of a Magnetic Ball Suspension System

However, feedback linearization control does not guarantee robustness in the presence of modeling errors. In [3], ∞ H control and sliding mode control was proposed. ∞ H control is a computation expensive method that presents good disturbance attenuation performance. In [4], sliding mode control and PID controller was discussed. In [5], the PID controller was discussed. The PID controller is a s...

Discrete time sliding mode control with application to induction motors

This work deals with a sliding mode control scheme for discrete time nonlinear systems. The control law synthesis problem is subdivided into a finite number of subproblems of lower complexity, which can be solved independently. The sliding mode controller is designed to force the system to track a desired reference and to eliminate unwanted disturbances, compensating at the same time matched an...

Control Using Sliding Mode Of the Magnetic Suspension System

This paper presents a proposition of sliding mode position controller of the magnetic suspension ball system . The magnetic suspension system (MSS) is a mechatronic system already acknowledged and accepted by the field experts. The design of a controller keeping a steel ball suspended in the air. In the ideal situation, the magnetic force produced by current from an electromagnet will counterac...

Discrete-time fuzzy sliding mode control for a vehicle suspension system featuring an electrorheological fluid damper

This paper presents real-time control characteristics of an electrorheological (ER) suspension system via a fuzzy sliding mode control algorithm which is formulated in a discrete-time manner by considering the sampling rate of an electronic control unit for a vehicle system. A quarter-vehicle system consisting of sprung mass, spring, tire and a cylindrical ER damper (shock absorber) is construc...
