Abstract

In this project, designing an active suspension system for a car turns out to be an interesting problem. When the suspension system is design, a one-half-car model (two of the four wheels) is used to simplify the problem to a one dimensional spring damper system. A good car suspension system should have satisfactory road holding ability, while still providing comfort when riding over bumps and holes in the road. When the car is experiencing any road disturbances (i.e. pot holes, cracks and uneven pavement), the car body should not have large oscillations and the oscillations should dissipate quickly. The road disturbances in this problem will be simulated by a step input. This step could represent the car coming out of a pothole. The solution for improve the output response of this project by designing a feedback controller such as PID controller and Negative Feedback controller. In addition, this project is to design a GUI to help user can sees the correlation between the output responses of the car suspension system when the input controller parameters are changes. The target result for this project show that the output response has an overshoot less and a settling time shorter.
