This paper presents a rigorous dynamic analysis for the Maglev system with controlled-PM electromagnets and robust zero-power-control strategy. A variable structure control (VSC) theory using new reaching law method is applied to the robust controller synthesis for reducing the control-voltage chattering and enhancing the suspension stability. Analytical expressions of the rms gap variation and the average regulation power loss under the excitation of random guideway irregularity are derived on the basis of this new control scheme by using frequency-domain approach. The power spectral density (PSD) method and the discrete frequency method of modelling the guideway roughness are both adopted to evaluate the overall vehicle ride dynamics. Numerical results gained from both approaches verify the feasibility and the superiority of applying this novel Maglev scheme to high speed transportation.
