Robust Identification and Control Design for Truck Cab Model Device

Abstract

The increasing attention on the applications of advanced robust control theories to automotive motivates the further investigation of truck cab model device for active vibration control.A balanced state-space model is necessary when designing a robust controller.Hence, the state-space frequency domain identification method is used to construct a model for model-based robust control design.Then H_∞ control theory and μ synthesis are readily to be used in order to calculate a controller for vibration suppression.The ν-tool is exploited to evaluate the quantitative margin for robust stability and performance.Finally, the closed-loop system achieved the satisfactory control results.
