Title: Controller
Inventor: YASUDA YOSHIHIDE
IPC: G05B13/02
Filed: 1989-03-31
Abstract: PURPOSE:To prevent overshooting without losing adaptability and to stably control humidity by correcting a set value applied to a PID arithmetic part at least based on a margin quantity and the variation of a process quantity. CONSTITUTION:A PID arithmetic part 2 inputs a process quantity PV and a set value SP1 from a process 1, executes a PID operation, and applys a control output MV to the process 1. A set value correction arithmetic part 4 uses a fuzzy rule based on the difference between a set target value TSP and a process quantity PV and the variation of the process quantity PV, obtains the corrected quantity of the set value SP, and applies the corrected set value to the PID arithmetic part 2. Thus the set value can be finely corrected for the input on various conditions, the overshooting at the time of settling the process quantity PV is prevented without damaging the quick response at the time of rising, and the humidity can be stably controlled.

Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To perform high speed operation of a scan function as restraining the malfunctions of a squelch by switching detecting speed of a noise squelch corresponding to a receiving state. SOLUTION: No scan signal is inputted in a controller 4 in a normal receiving state, and the controller 4 is controlled so that the capacitance of a variable capacitance capacitor VC is made large. In such a case, the malfunctions of opening and closing the squelch are reduced through the followup ability of output of a noise amplifier 2 in a noise squelch circuit 1 is deteriorated, and since the capacitance of the capacitor is large, the time constant becomes large as well. When the scan signal is inputted in the controller 4 at a special receiving state like scanning. etc., the controller 4 is controlled so that the capacitance of the variable capacitance capacitor VC is made to be small.  At this time, high speed operation is enabled since the capacitance of the capacitor is made to be small, the time constant is also made to be small, and the rise of the output of the noise amplifier 2 in the noise squelch circuit 1 is speeded up, so that accelerated operation becomes possible.
