Since the performance of the teleoperation systems can be considerably degraded by time-delay of communication channels and uncertainty in various parts of such systems, the main objectives of the controller design in loads of different structures of the bilateral teleoperation system are to preserve stability and tracking performance of these systems in spite of aforementioned sources of uncer...

In this paper, we propose a design method of an adaptive PID controller based on output feedback for nonlinear systems with a higher order relative degree and disturbances. To realize an adaptive PID control system, we introduce a PFC for a nonlinear system which does not satisfy OFEP(Output Feedback Exponentially Passive) conditions and design an adaptive feedforward input with a structure of ...

TCP Flows Based on H∞ Optimal Control Theory Li Yu* Zibo Shi Kun Chen Yantai Shu Department of Computer Science, Tianjin University, Tianjin, 300072, P.R. China Abstract A robust PID controller for active queue management (AQM) based on modern H∞ optimal control theory is presented in this paper. Taken both robustness and closed loop performance into consideration, most desirable parameters val...
