dc.description.abstractThe main purpose of vehicle suspension system is to isolate the vehicle main body from any road geometrical irregularities in order to improve the passengers ride comfort and to maintain good handling characteristics subject to different road profile. This dissertation aim at establishing a mathematical model and a control strategy for a nonlinear hydraulically actuated active suspension system. A model of nonlinear, four Degree of Freedom (DOF) half vehicle active suspension system with hydraulic actuator dynamics and a similar nonlinear, four DOF half vehicle passive suspension system model was developed using Matlab/Simulink environment. A control system consisting of two controller loops was also developed, namely inner loop controller for force tracking control of the hydraulic actuator and outer loop controller to resist the effects of road induced disturbances. The outer loop controller employed a proportional integral and differential (PID) control strategy. On the other hand, a proportional integral and differential (PID) force feedback control scheme was employed in the inner loop controller to stabilize the hydraulic actuator in such a way that it is able to supply the actual force as close as possible with the optimum targeted force supplied by the PID controller. Two types of road (discrete and random) inputs were employed and a simulation study using Matlab/Simulink environment was performed to test the effectiveness and robustness of the control scheme. The performance of the active suspension system was assessed by comparing it response to that of passive suspension system. Results obtained shows that, the active suspension system developed a good dynamic response and a better ride comfort when compared to the conventional passive suspension system.en_US
