Adaptive PID control with an adjustable identification interval is proposed. The difficulty of choosing a suitable sampling time for control systems is prevented. The identification algorithm depends on that the identification interval is different from the sampling interval. Tuning of the PID controller is based on an adaptive first-order plus dead time model at each identification step. The model is obtained directly from an identified second-order one. Two illustrative examples are presented to show the considerable Promise that the method exhibits.
