Innovative Systems Design and Engineering
Modeling, Design and Simulation of Active Suspension System Frequency Response Controller using Automated Tuning Technique
Abstract
Car suspension system is a mechanism that separates the car from the tire. The objective of the suspension system is to improve a ride quality by ensuring passenger’s comfort and good car road handling when the car is subjected to an input excitation. The dynamics of the suspension system was mathematically modeled. The system transfer function determined. The suspension system performance characteristics of overshoot and settling time set at not more than 5% and 5seconds respectively. Frequency response controller was designed by using the MATLAB function sisotool in the automated tuning technique. The result of the simulation indicated that the overshoot and settling time 2.97% and 3.95seconds respectively. The design requirement satisfied.
