Intelligent Cuckoo Search Algorithm of Skyhook Controller for Semi-Active Suspension using MR Damper

This paper introduces the use of Cuckoo Search Algorithm (CSA) to tune the Skyhook controller for semi-active suspension system in furtherance of increasing and enhancing the ride comfort and vehicle stability. In the meantime, the intelligent approach with Skyhook-CSA is compared with uncontrolled passive system. The performance of the Skyhook controller is optimized by CSA, respectively. The mean square error (MSE) of the system is set as an objective function for the optimization process of the proposed controller. The performance of the Skyhook-CSA controller is compared with the passive system in terms of sprung acceleration, sprung displacement and unsprung displacement. The random road profile with 2.6 Hz frequency is set as the disturbance of the system. The simulation results reflect that the controller offers a significant improvement in ride comfort and vehicle stability by 15.47% of MSE.
