Abstract
The value of a self-tuning adaptive semi-active control scheme for automotive suspension systems is discussed in this paper. The current vehicle suspension system uses fixed-coeffcient springs and dampers. The ability of vehicle suspension systems to provide good road handling and improve passenger comfort is usually valued. Passive suspension allows you to choose between these two options. Semi-Active suspension(SAS), on the other hand, can provide both road handling and comfort by manipulating the suspension force actuators directly. The semi-active suspension system for a quarter car model is compared to passive and various controllers such as Proportional-Integral, Proportional-Integral-Derivative, Internal model control (IMC)-PID, IMC-PID with filter, FUZZY, and Adaptive-network-based fuzzy inference system(ANFIS) in this analysis. This research could be relevant in the future for designing better car suspension adjustments to eliminate vertical jerks and rolling motion experienced by the vehicle body on bumps and humps.

1.1 Motivation and backgroundSuspension systems are vital for vehicles’ health and their life expectancies, and for rider’s health, safety, and comfort
Ride comfort is influenced by several elements while driving over a speed bump including vertical spring action, the oscillation that occurs during the settling process, the time required to settle after oscillatory behavior, and the maximum heave motion are typically associated with a smooth ride
Summary
Suspension systems are vital for vehicles’ health and their life expectancies, and for rider’s health, safety, and comfort. Developing and designing an advanced controller for semi-active suspension systems will reinforce the existing semi-active suspension systems and provide better resistance against the vertical acceleration caused by road disturbances. The underlying motive for conducting a comparative study of various controllers’ responses to speed bumps is because speed breakers are a common sight in India and an indicator of disruption in road transport and safety. A control technique for linear time-invariant based semi-active suspension for a quarter car model are presented. The study focuses on bumps and humps, which are specified by the Indian government in section IRC 991988 of the Indian Road Congress and customary design approved by different manufacturers all over India. Each of the bumps and humps considered has a distinct shape
