In essence, fuzzy control design is recast as a nonlinear control approach using absolute stability theory, sliding mode control, and adaptive fuzzy control [4, 23]. This allows Mamdani fuzzy control to easily achieve multi-objective goals by simply setting some fuzzy control rules under one criterion and others under a different performance criterion.
