  ABSTRACT: In this paper, an integrated powertrain control of gearshift for automatic transmission is developed: engine control by torque regulation is incorporated to suppress the shock of output shaft torque, whilst a clutch slip controller is applied to transfer the engine torque to driveline system, which is aimed to regulate clutch slip speed. The proposed approach ensure the powertrain system stable, and the shift time can be controlled by clutch slip controller even if with the absence of engine control. At last, taking 1-2 upshift for example, simulation results are presented and discussed in the final chapter of this paper.

• Conference Proceeding: Static output feedback control of the linear system with parameter uncertainties

  ABSTRACT: This paper investigates robust static output feedback (SOF) control problem for the linear systems with parameter uncertainties. Based on the structure of the uncertainties, the systems are separated into linear time invariant (LTI) systems and linear parameter varying (LPV) systems. Then, a class of uncertain systems with norm-bounded perturbations is discussed for both LTI systems and LPV systems. Moreover, robust H_∞ control problem is mentioned as well, which can be reduced to a generalized robust SOF stabilization problem. The proposed approach is applied to active suspension control to illustrate its application at last, and it can be shown that the results in this paper are valid.
