Abstract

A new control strategy for semi-active suspension system in a road vehicle called Jerk Driven Damper (JDD) is proposed and analyzed in this paper. The control strategy for JDD system is extremely simple and it involves very common logic. JDD system requires a two state controllable damper and jerk sensor. A semi-active damper is incorporated into a single degree of freedom (1DOF) quarter car model subjected to base excitation. Here, two types of positive amplitude half sinusoidal type speed breakers (severe and smooth) with same height are considered as input to the vehicle. These proposed road inputs are used for study and simulation of passive, sky-hook (SH) control and acceleration driven damper (ADD) suspension systems. The optimality of JDD is examined over SH and ADD control which is observed with both ‘severe’ and ‘smooth’ speed breakers. It is shown that the JDD control shows better reduction in vertical acceleration when the vehicle comes across severe breaker. Later the vertical body acceleration response (comfort objective) of JDD control strategy is compared with various types of well-studied control strategies and shown to have better isolation
