For the tracking control problem of vehicle suspension, a robust design method of adaptive sliding mode control is derived in this paper. The influence of parameter uncertainties and external disturbances on the system performance can be reduced and system robustness can be improved. The adaptive sliding mode controller is designed so that the practical system can track the state of the referen...

Part 1 of this paper proposed a methodology for the efficient determination of gradient information, when optimising a vehicle’s suspension characteristics for ride comfort and handling. The non-linear full vehicle model, and simplified models for gradient information has been discussed, and validated. In this paper, the simplified models presented in Part 1 are used for gradient information si...

With active vehicle suspension, one can tailor a vehicle's response to load and inertial disturbances without affecting the vehicle response to road disturbances. This decoupling is achieved in (Williams and Best 1994) and (Smith and Wang 2002) using a filtered combination of measured signals. These filters, which we call Williams filters, require exact knowledge of certain vehicle parameters i...

The paper presents finite element (FE) model development and experimental validation for a truck tractor with a three axle single drop lowboy trailer. The main objective of this research activity was to create a simplified, three dimensional virtual FE model, applicable for computer simulation of dynamic interaction between a vehicle and a bridge or road structure. Such model should provide a r...

This paper is concerned with full vehicle nonlinear active suspension systems, in which each suspension unit consists of three components: a nonlinear spring, a nonlinear damper and a nonlinear hydraulic actuator. An artificial intelligence Neural Control technique has been presented in this paper to design a robust controller for full vehicle nonlinear active suspension systems. The advantage ...

This work proposes a new piezoelectric transducer system with four freedoms of movement modelled and evaluated by mechatronic techniques. The proposed modelling techniques (finite element bond graph) were performed in 20-Sim framework attached to the ANSYS software. established harvester has ability increase driver's comfort when travelling on several types road surfaces. is designed investigat...
