A fully active suspension and preview control is utilized to improve ride comfort, which allows increased travelling speed over rough terrain. Previous research is extended and the relevant implementation issues are addressed. Specifically, the methodology of model predictive control has been applied to explicitly address suspension saturation constraints, suspension rate limits, and other syst...

The Vickers J12 cell counter uses an optical hydraulic counting system to perform rapid automatic counts of leucocytes and erythrocytes in liquid suspension. The effect of sample storage, the use of different diluents, variation in cell dimensions and other relevant factors have been studied. A counting accuracy of +/- 1.19% for replicate erythrocyte counts and +/- 2.94% for leucocyte counts wa...

This paper presents a novel approach to the design of road adaptive active suspensions via a combination of linear parameter-varying control and nonlinear backstepping techniques. Two levels of adaptation are considered: the lower level control design shapes the nonlinear characteristics of the vehicle suspension as a function road conditions, while the higher level design involves adaptive swi...

This paper describes the structural and thermal modeling of a Micro Electro Mechanical System (MEMS) z-axis angular gyroscope. The gyroscope consists of a oscillating proof mass supported by a suspension made up of six concentric interconnected rings rigidly attached to an anchored frame. The device is capable of measuring angular displacement through precession of the proof mass line of oscill...

Abstract — In this paper we design a new type of hydraulic Energy-Regenerative vibration active suspension system. The system has continuous change of damping force from zero to the maximum value and high energy conversion efficiency. Also we designed and simulated an adaptive back-stepping sliding mode variable structure controller. The simulation results show the designed controller has good ...

ARTICLE INFO An agricultural tractor seat with passive suspension system gives a number of advantages when compared with currently available seat designs. Analysis on the vibration of tractor seat suspension system by using the different types of the suspension system is carried out for the different types of operation and analyze the suspension system separately to find out the reduction in th...
