Analysis of the Control Accuracy in Steady State of a Hybrid PI Controller

The control accuracy in steady state of a developed hybrid PI (with conventional P and fuzzy I components) controller is investigated in respect with proportional gain coefficients and integral constant values, the period of measurement of the control variable and the period of the pulse width modulator (PWM) by means of which the heater is being controlled. Relevant conclusions were made on the basis of the conducted experiments.
