Abstract

With the growing number of automobiles on the road and the introduction of electric and hybrid vehicles, it has become critical to lower each vehicle's energy usage., as several renewable methods are used on a large scale for harvesting energy from the various systems of the vehicle, including energy harvesting using suspension systems. In this paper, the power generation system was derived and modeled using the non-linear suspension system for a full model of the vehicle using the MATLAB-SIMULATION, where the system consisting of a hydraulic cylinder, piston, a spool valve, and hydraulic motor. The system's performance characteristics were compared to those of passive and active suspension systems, and the system's performance was found to be comparable to that of the active system. Three different pressure levels (10, 30, and 50 bar) were used, along with three different input signals (random, sinusoidal, and square) and a fractional order proportional integral derivative controller (FOPID). The results showed the performance characteristics of the regenerative suspension systems can be close to the performance characteristics of active suspension systems.
