-This study addresses a fuzzy Lyapunov method for the stability analysis of time-delay fuzzy systems subject to external disturbances. The Takagi-Sugeno (T-S) fuzzy model and parallel distributed compensation (PDC) scheme are first employed to design a nonlinear fuzzy controller in order to stabilize the time-delay fuzzy systems. According to the controlled system, the H infinity criterion is d...

Many processes in industry exhibit time-delay in their dynamic behavior. Time-delay is mainly caused by the time required to transport energy, information or mass, but it can be caused by processing time as well. There are also many cases when compensation of measurable disturbance is required. In light of these facts, the goal of this paper is to design predictive algorithm for control of time...

This paper discusses the compensation of the transmission delay in a networked control system (NCS) with a state feedback, which possesses a randomly varying transmission delay and uncertain process parameters. The compensation is implemented by using a buffer in the actuator node and a state estimator in the controller node. A Linear Matrix Inequality (LMI) based sufficient condition for the s...

High control bandwidth is usually restricted in a photoelectric tracking system (PTS) based on Charge-Couple Device(CCD) with time delay, which hinders good performance. Generally, model-based delay-compensation controller called Smith predictor (SP) can help increase the gain to promote by separating delay from loop. However, performance promotion insufficient because still stays forward chann...
