PROBLEM TO BE SOLVED: To enable high-accuracy control and regulation by finding a suitable PID control parameter without requiring any trial operation by operating a step response from a driving signal to a static pressure detecting signal applied from a PID control means to a centralized sending means, finding the PID control parameter and outputting it to a PID control means. SOLUTION: In a regulator for the duct inside pressure control system of an air conditioner for feeding air into a chamber 1 composed of three chambers to condition air, a step response operating means 105 operates the step response from a fan driving signal 108 to a static pressure detecting signal 107. Then, the suitable PID parameter is found by a PID parameter operating means 106 while using the provided step response waveform and inputted to a PID control means 103. Therefore, the suitable PID control parameter of the PID control means 103 is found without applying any test signal to a plant actually, the control and regulation of a pressure control system can be performed, and the trial operation on the job site is unnecessitated. |
