Based on a derivative estimator and eigenvalue configuration, a second-order nonsingular terminal sliding mode decomposed control method is proposed for a class of multivariable systems with uncertain systemic matrix and input matrix. The proposed method is suitable for high-dimensional multivariable systems, which can simplify the design of controller, eliminate the chattering phenomenon and realize robust hierarchical control. The Simulation results show the effectiveness of the design method.
