Abstract :
A new Smith predictor for control of an unstable process with time delay and a process with an integrator and long dead-time is proposed. The controller decouples the setpoint response from the load response. The design approach is based on standard forms of the closed loop system response and on the Nyquist stability analysis. Simulation results show high performance for the setpoint response and load disturbance rejection
