dc.description.abstractBuilding a reliable control algorithm for a mechatronic suspension can be tricky because of the unpredictable nature of the system and the necessity to achieve a good trade off the requirements of road grip and comfort of passengers. This research work assesses the performance among two control methods— H ∞ and “Linear Quadratic Regulator, or LQR”—applied to a mechatronic suspension system. An active suspension system utilizes sensors and actuators in addition to the elastic element and shock absorbers of the traditional suspension structures. A quarterly automobile model consisting of 2 degrees of freedom is used when designing the suspension system of the car. A mechatronic suspension system combines software, electrical, and mechanical partto improveng the car handling and convenience of passengers on the road. The suspension deviation, wheel displacement, and upward acceleration of the car frame are the performance parameters taken into consideration in this thesis. The goal is to strike a perfect balance while achieving minimum readings of car chassis acceleration and wheel deflection demonstrated by each controller when steady state error approaches zero from the suspension response. The body acceleration and wheel deflection affect the passenger comfort and road handling respectively. Three separate sections make up this thesis. The literature covering H ∞ control, Linear Quadratic Regulator control, and active suspension designs is examined in the first chapter. With MATLAB/ Simulink software, the active suspension structure is mathematically modeled and simulated in the second part of this work. The assessment and examination of the active suspension system's performance standards for ride comfort and road handling under various driving circumstances and parameter changes are covered in the third chapter.
