Controller Design for Passive Suspension System of Vehicles using MATLAB.

In this project, we are finding the governing equation of motion for the system provided which is passive suspension system of vehicles. The open loop transfer function is obtained so that we can design a proportional controller for the system. The stability analysis is very crucial for any system while using any controller. The controller gain value (K) is to be chosen such that the system remains stable even after applying any external force or disturbance input. For stability analysis and finding the appropriate value of the range of K, we are using the Routh-Hurwitz Criteria and Root locus plot. For further validation and analysis, we are using MATLAB Simulink to model the system and find the outputs after applying the desired proportional controller so that the percentage maximum overshoot does not exceed the value of 10%.
