“…The existing control strategies are divided into three categories: first, the methods based on 1 School of Mechanical Engineering, Sharif University of Technology, Tehran, Iran 2 School of System Design Engineering, University of Waterloo, Waterloo, Ontario, Canada heuristic procedures, such as fuzzy logic [2][3][4] and rulebased procedures; 5,6 second, the methods based on instantaneous optimization of an equivalent FC function which shows the overall FC of the vehicle; [7][8][9] third, the methods based on global optimization by which the controller's global optimum solution is found, such as particle swarm optimization (PSO), 10,11 simulated annealing 12,13 and dynamic programming. 14,15 The electric assist control strategy (EACS) is one of the rulebased control strategies in which the main power source is the ICE while the electric motor supplies the rest of power. According to this strategy, when the ICE is working far from its optimum operating point (e.g.…”
