Object manipulation techniques in robotics can be categorized in two major groups including manipulation with and without grasp. The aim of this paper is to develop an object manipulation method where in addition to being grasp-less, the manipulation task is done in a passive approach. In this method, linear and angular positions of the object are changed and its manipulation path is controlled...

Semi-active Fuzzy control of quarter car system having three degrees of freedom and assembled with magnetorheological (MR) shock absorber is studied in present paper. First, experimental work was performed on an MR shock absorber under different excitation conditions to obtain force-displacement and force-velocity curves. Then, for the application of experimental data in semi-active quarter car...

The plant and control optimization problems are coupled in the sense that solving them sequentially does not guarantee system optimality. This paper extends previous studies of this coupling by relaxing their assumption of full state measurement availability. An original derivation of first-order necessary conditions for plant, observer, controller, and combined optimality furnishes coupling te...

In the vehicle development, the importance of reducing road noise is increasing because of the increasing popularity of quiet electric vehicle. The suspension plays an important role on the mechanism of the structure born road noise. As the countermeasure for reducing road noise, low stiffness suspension bush is often used from the point of view of vibration insulation. However, in general, to ...

The hydraulic active suspension systems have certain nonlinear and time-varying behaviors. It is difficult to establish an appropriate dynamic model for model-based controller design. Here a novel neural network based sliding mode control is proposed by combining the advantages of the adaptive, radial basis function neural network and sliding mode control strategies to release the model informa...

Automotive is one of the most important industries in world, which lead to a need for continuous improvement vehicles and their internal systems. Suspension systems have been improved better vehicle performance passenger comfort, keeping tire contact with road surface. Active suspensions require optimal control modulate flow energy generate force by implementing active actuators able provide ne...
