Comfort travel is order of the day for any automotives in spite of the road conditions. Suspension system holds whole and sole responsibility of providing comfort to the occupants. Intensity of the disturbance originated from road varies with its condition ranging from minimum in case of normal road (Moderately rough) to maximum in case of pot hole or speed breaker. Accordingly stiffness of the...

In this paper active suspension with linear electric motor has been designed. The active suspension is often hardly rejected for its big energy consumption. This contribution deals with direct real-time energy control in suspension system. The linear electric motor is used as an actuator. This motor can in specific situation generate the energy for next use. The H-infinity controller has been d...

The active suspension has undoubtedly improved the performance of vehicle, however, trend “lowcarbonization, intelligence, and informationization” in automotive industry put forward higher more urgent requirements for system. researchers favor energy regeneration technology with safety, comfort, high regenerative efficiency. In this paper, we review research progress structure form, optimizatio...

The paper focuses on the practical implementation of a new robust control method to an automotive active suspension system using skyhook and adaptive active force control (SANAFC) strategy. The overall control system essentially comprises four feedback control loops to cater for a number of specific taks. Neural networks (NN) with modified adaptive Levenberg-Marquardt (LM) learning algorithms w...

This paper reported the numerical analysis technique to investigate the influence of spring stiffness in automotive suspension towards improving the vehicle ride and performance. There are three type of spring’s stiffness categories which have been used to conduct the numerical analysis; soft, medium and hard. Using the full vehicle model and front suspension mathematical model, the study on ro...

An active suspension system has been proposed to improve the ride comfort. A quarter-car 2 degree-of-freedom (DOF) system is designed and constructed on the basis of the concept of a four-wheel independent suspension to simulate the actions of an active vehicle suspension system. The purpose of a suspension system is to support the vehicle body and increase ride comfort. The aim of the work des...

This article is about the problem of control system synthesis for an active suspension with not-ideal actuator under kinematic constrains. paper investigates influence hysteresis and dead zone in on efficiency system. To reduce a method discontinuous systems proposed. The proposed reduces sensitivity to disturbances caused by non-ideal actuator. It enables fourfold expansion distribution range ...
