摘要： PROBLEM TO BE SOLVED: To provide a duplex automatic switching control device for fluid distribution line capable of automatically switching a regulating valve while minimizing the fluctuation of a control target value, and reducing the cost while avoiding enlargement of its actuator part without extending the range of the regulating valve.
SOLUTION: In normal time, the aperture of a main regulating valve 12A is automatically adjusted, in a state where driven cutoff valves 13B and 14B are fully closed and main cutoff valves 13A and 14A are fully opened, so that a flow rate 11 detected by a flowmeter 15 becomes a flow set value 16, while in the event of abnormality of the main regulating valve 12A, the aperture of the main regulating valve at that time 12A is held, the openings of the driven cutoff valves 13B and 14B are changed from full close to full open while gradually throttling the main cutoff valve 13A from full open to full close, and the aperture of a driven regulating valve 12B is automatically adjusted so that the flow rate detected by the flowmeter 15 becomes the flow set value 16.

摘要翻译：要解决的问题：提供一种用于流体分配管线的双相自动切换控制装置，其能够在最小化控制目标值的波动的同时自动切换调节阀，并且降低成本，同时避免其致动器部件的扩大而不延伸调节阀的范围。解决方案：一般来说，主动调节阀12A的开度在被驱动的截止阀13B和14B完全关闭并且主截流阀13A和14A完全打开的状态下自动调节，使得流量流量计15检测出的流量设定值16成为流量设定值16，而主调节阀12A发生异常的情况下，保持主调节阀12A的开度，驱动截止阀13B，14B的开度从完全接近全开，同时将主截流阀13A从全开到全关闭逐渐节流，并且自动调节从动调节阀12B的孔径，使得由流量计15检测的流量变为流量设定值 16.版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To approach an optimum pattern with a short control step and in a short time by deciding the increase/decrease direction and increase/decrease quantity of a control parameter from a simulation pattern, and calculating the weighted average of the increase/decrease direction and increase/decrease quantity of each control parameter to each measured variable taking the significance into consideration. SOLUTION: A learning procedure prepares/sets a simulation pattern in a response pattern preparation 2 for PI controller learning by the simulation of an object plant or the step response test 1 of a real machine and performs automatic learning in an automatic learning algorithm 3. An adjustment procedure calculates the time constant of an object plant according to time constant calculation 4 and decides the interval of control time by deviding the time constant by a prescribed number. Further, fuzzy inference 5 automatically adjusts a control parameter such as a proportional gain on the basis of automatically learned results. That is, a real pattern is calculated from control time and a controlled variable, a simulation pattern corresponding to it is selected, the increase/decrease direction, etc., of the control parameter is decided and increase/decrease quantity is decided with fuzzy evaluation.

摘要： PROBLEM TO BE SOLVED: To enable easily use of this system in a short time, without grasping the control system of a whole plant by operating an objective plant, selecting a simulation pattern equivalent to a real pattern obtained from a relation between a control time and a controlled variable, and deciding the increasing and decreasing direction and increasing and decreasing amounts of plural control parameters. SOLUTION: A simulation pattern is prepared by the simulation of an objective plant or a step response test 1 of a real machine, and automatic learning is operated by an automatic learning algorithm 3. In this case, at the time of automatically adjusting the plural control parameters of the control adjuster of a minor loop, the optimal patterns of a control time and a controlled variable have been previously set, and the plural control parameters are increased or decreased so that a relation between the control time and controlled variable of the objective plant can be set as plural simulation patterns. Then, the objective plant is operated, a real pattern is obtained from the relation between the control time and the controlled variable, a simulation pattern equivalent to this real pattern is selected, and the increasing and decreasing direction of the plural control patterns is decided.
