Abstract :
This paper presents a remote process control application trough the Internet, considering the negative effects of TCP/IP-based networks over computer control due to time-varying sampling period. A controller design approach that uses time-varying observers and state feedback controllers designed by means of linear matrix inequalities (LMI) and quadratic Lyapunov functions helps in overcoming the outlined problem. An experimental setup for remote DC motor control shows the applicability of the approach in a real implementation.
