Abstract
The closed-loop feedback structure of PID generalized predictive control (PID - GPC) is proposed, then small-gain criterion is used to obtain a sufficient condition for the robust stability of PID - GPC under the condition of model-plant mismatch ( MPM) . Further more, the influence of PID - GPC parameter tuning on its robustness is analyzed in frequency domain.
