Speed control of hybrid electric vehicle using PSO based fractional order PID controller

Abstract

In this paper, a conventional Proportional-Integral-Derivative (PID) and fractional-order PID controller have been designed for the speed control of hybrid electric vehicle. The parameters of both PID and FOPID controller are optimized using Practical Swarm Optimization (PSO) method taking Integral of Absolute Error (IAE) as the fitness function. The performance of the implemented controller is analyzed in terms of transient and steady state specifications. A performance comparison is carried out among the implemented controllers in the presence of vehicle parameter variations.
