The invention discloses an amplitude limiting threshold variable flexible control method for a large complex system. The method comprises the following steps: calculating a first deviation of the large complex system according to the control target and the output of the large complex system; determining forward control system parameters of the large complex system, and obtaining forward control system output of the large complex system according to the first deviation; calculating a second deviation between the output of the forward control system and nonlinear amplitude limiting; determiningreverse control system output of the large complex system and third deviation corresponding to the reverse control system output according to the reverse control system parameters and the second deviation; and adjusting the output of the forward control system based on the third deviation. According to the invention, the negative feedback is superposed to the output of the forward large-scale complex system control system through the reverse control method, the equipment faults of the large-scale complex system are reduced, and the service life of the large-scale complex system is prolonged.
Description
technical field [0001] The present application relates to the technical field of large-scale complex system operation control, in particular, to a flexible control method with variable clipping thresholds for large-scale complex systems. Background technique [0002] There are many working conditions in large and complex systems, and there is a high degree of correlation and coupling between systems and equipment. The integrated control system of a large complex system is similar to the human brain, which is an important guarantee for the safe, reliable and efficient operation of a large complex system, and directly affects the availability and security of a large complex system. [0003] The working condition refers to the working state of the equipment under the conditions directly related to its action. The working condition of a large complex system will be switched continuously according to the task needs during the operation process. When the working conditions are sw...
