Abstract
The term "active suspension" refers to a suspension system that includes active components such as Magneto-rheological (MR) dampers & actuators, PID controller with closed feed forward loop. The active suspension is superior to passive suspension in terms of ride quality and vehicle handling due to reduction in vertical amplitude disturbance. To enhance ride quality and comfort, the active suspension's actuator applies forces to the suspension system as a whole. In this study, the early stages of modelling a passenger vehicle's active suspension are shown. An early suspension control system for the car is displayed and explained. It has been found that the active suspension reduces vehicle body accelerations and suspension deflections, improving ride quality. Several mathematical models, known as lumped parameter models, have been used to explore vehicle dynamics. Two degrees of freedom (quarter car model), four degrees of freedom (half car model), and seven degrees of freedom are among the mathematical models that have been studied in this research project (full car model). SIMULINK® is used to study these systems in this paper.
