摘要： PROBLEM TO BE SOLVED: To provide a method and device for suppressing the hunting of an operation signal since a large stress is partially imposed on the valve of control equipment due to the occurrence of the hunting of the operation signal, and there is any possibility that equipment failure is caused although apparent main controlled variable are stable.
SOLUTION: An operation signal SU is outputted to control a plant 30 on the basis of a target value SR, and controlled variable SY being the output of the plant are fetched, and the plant 30 is feedback-controlled according to a deviation signal EY between the target value SR and the manipulated variable SY. When the vibration of the operation signal SU is detected, the parameter of a controller 20 is set to a predetermined value for attenuating the vibration. Furthermore, the vibration of the deviation signal EY is evaluated, and when it is decided that the vibration of either the operation signal SU or the deviation signal EY is not present, the parameter is reset to another predetermined value or the original value. Thus, it is possible to suppress the hunting of the operation signal, and to protect instrumentation equipment such as a valve. Thus, it is possible to improve the quality of a product manufactured by equipment to be controlled as a result.

摘要： PROBLEM TO BE SOLVED: To provide a membrane filtration module for detecting a functional deterioration of a filtration membrane which is capable of measuring the properties of a water filtrate as a water to be tested in situ without changing the properties of a water filtrate and does not need a lot of steps of sensor construction works at the time of exchange of a membrane filtration module and to provide a membrane filtration operating device.
SOLUTION: The membrane filtration module is provided with a communication device by incorporating a sensor device into a filtration water discharge port of a case housing of a membrane filtration module. Thus, the properties of the filtration water can be measured. If the membrane filtration module is exchanged using, for example, ad hoc communication, the adjustment of the communication system is not needed anew. Although passage light of the filtration filter is set to a certain level because the capture of an impurity material is little when there is no leak from the filtration membrane, the passage light is reduced because the impurity material that leaks into the filtration water can be captured by the filtration filter and light is shaded by the captured impurity material of the filtration filter. The leak due to the filtration membrane failure can be detected and the failure is detected.
