This paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. Since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

Flexible structures (such as long-span suspension bridges which undergo wind or earthquake excitations) exhibit complex dynamic behavior. Due to high cost of strengthening such structures, as well as the technological advances in recent years, much attention has been given to using innovative means of enhancing structural functionality and safety against natural hazards. Among the methods used ...

In this paper, a novel H? control method in two time scales is proposed for active suspension systems. Two are considered based on the natural scale separation existing systems, i.e. sprung mass part corresponding to fast dynamics and unsprung slow dynamics. Singular perturbation theory used establish dual model design controller. Compared with commonly controller, time-sharing dynamic characte...

This paper presents a new control algorithm for controlling randomly switching systems under random disturbance. The proposed controller is designed based on dual prescribed sliding mode and modified Riccati-like equation. surface of the includes two parts: classical type performance. combined provides strong disturbance rejection capability system. Riccati equation functionalities: (i) associa...

In this paper, the development of a semiactive suspension control of quarter car model using fuzzy-based controller has been done. The quarter car model to be used here can be described as a nonlinear two degrees of freedom system which is subject to excitation from different road profile. The semi-active control is designed as the fuzzy control inferred by using two single input rule fuzzy mod...

The suspension system and socket fitting of artificial limbs have major roles and vital effects on the comfort, mobility, and satisfaction of amputees. This paper introduces a new pneumatic suspension system that overcomes the drawbacks of current suspension systems in donning and doffing, change in volume during daily activities, and pressure distribution in the socket-stump interface. An air ...

In this paper, a decentralized integrated control structure ...
