A switching fuzzy control method for the magnetic active suspension system

A switching fuzzy control system is proposed for dealing with the non-linear dynamics of electromagnetic suspension system. With two fuzzy sub-controllers and a switch engine, the switching fuzzy control system is flexible to cover changeable initial conditions with less computational cost. For satisfying the coupling constraint on positions of four floaters, a global self-supervisor with feedback structure is designed to control all four fuzzy subsystems. Simulations on the magnetic suspension with three different initial position settings demonstrated the efficiency of proposed method.
