Vehicle primary suspensions
Primary suspension is the term used for suspension components connecting the wheel assemblies of a vehicle to the frame of the vehicle. This is in contrast to the suspension components connecting the frame and body of the vehicle, or those components located directly at the vehicle’s seat, commonly called the secondary suspension. Usually a vehicle contains both primary and secondary suspension system but primary suspension is chosen for control. There are two basic types of elements in conventional suspension systems. These elements are springs and dampers. The role of the spring in a vehicle’s suspension system is to support the static weight of the vehicle. The role of the damper is to dissipate vibrational energy and control the input from the road that is transmitted to the vehicle.

Typically a fuzzy logic controller is composed of three basic parts; (i) input signal fuzzyfication, (ii) a fuzzy engine that handles rule inference and (iii) defuzzification that generates a continuous signal for actuators such as control valves.
The fuzzification block transforms the continuous input signal into linguistic fuzzy variables such as small, medium, and large. The fuzzy engine carries out rule inference where human experience can easily be injected through linguistic rules. The defuzzification block converts the inferred control action back to a continuous signal that interpolates between simultaneously fired rules.
