T-S Fuzzy Model Based Control Strategy for the Networked Suspension Control System of Maglev Train

Abstract EN

The control problem for the networked suspension control system of maglev train with random induced time delay and packet dropouts is investigated.

First, Takagi-Sugeno (T-S) fuzzy models are utilized to represent the discrete-time nonlinear networked suspension control system, and the parameters uncertainties of the nonlinear model have also been taken into account.

The controllers take the form of parallel distributed compensation.

Then, a sufficient condition for the stability of the networked suspension control system is derived.

Based on the criteria, the state feedback fuzzy controllers are obtained, and the controller gains can be computed by using MATLAB LMI Toolbox directly.

Finally, both the numerical simulations and physical experiments on the full-scale single bogie of CMS-04 maglev train have been accomplished to demonstrate the effectiveness of this proposed method.
