This paper proposed a PID controller for a semi-active suspension system with a hydraulic single-tube shock absorber. A quarter-car model with a sub-model of the single-tube shock absorber was used to perform the simulation. In comparison with the non-controlled system, the damping performance of the controlled system increased significantly.

In this present paper, the road profiles are generated according to the ISO 8606:2016 standard to compare the differential of the road profile when changing the conditions. The semi-active suspension techniques are the solution to this problem and capable of reducing road vibrations effectively. The vertical quarter car model is installed with semi-active suspension system using Electrorheological shock absorber (ER damper) also considered to study the response of the vehicle to the road profile.

The main idea of this method is that the force of the controlled damping will change, so that the magnitude of the force is equal to that of the spring, but the direction of the forces is the opposite. This will reduce the vertical acceleration of the vehicle body. The simulation results in the time domain have been clearly shown by using the balance control methods. The root mean square of the vertical displacement, pitch angle and their accelerations decrease by 25-50%, compared to the passive suspension system.

Semi-active (SA) suspensions are those which otherwise passively generated damping or spring forces modulated according to a parameter tuning policy with only a small amount of control effort. SA suspensions, as their name implies, fill the gap between purely passive and fully active suspensions and offer the reliability of passive systems, yet maintain the versatility and adaptability of fully active devices.
