الملخص الإنجليزي

In this study, we propose a new control strategy for the control of an electro-hydraulically controlled active suspension system.

A PID, along with fuzzy control is employed to form a switch between bump isolation and inertial load rejection strategies.

Our study propose a special construction of the suspension system where the electro-hydraulic actuator is to be placed in series with the conventional passive one to form a special case of low frequency active suspensions.

The full dynamics of the electro-hydraulic servo valve and hydraulic actuator are employed.

The proposed control strategies are applied to a quarter car model.

Response of the proposed control strategy is tested for different road profiles and riding conditions including car chassis rolling effect when cornering and pitch movements when braking/ accelerating.

Results show superior performance of our modified controller over passive suspensions and many other controllers of previous studies.

Simulations of our proposed controller provides better passenger comfort as it lowers maximum body acceleration by 60 % and with reduction in body travel by 91 % of that of passive one.

Our proposed control strategy also show better road handling and car stability over a whole range of road and inertial disturbances
