Table 1

Comparison chart for various control strategies.

Methods	Structural complexity	Computation time	Type of solution	Requirement of a priori knowledge
Fuzzy logic	N	S	G	Y
Genetic algorithm	Y	M	G	N
Particle swarm optimization	N	M	G	N
Energy consumption minimization strategy	Y	S	L	N
Pontryagin’s minimum principle	N	S	L	Y
Dynamic programming	Y	M	G	Y
Model predictive	N	S	G	N
Stochastic dynamic programming	Y	M	G	N
Neural network	Y	S	G	Y

G = global, L = local, N = no, Y = yes, M = more, and S = small.
