Abstract

The embodiment of the invention provides an optimization method and device for specified controller parameters. The method comprises the steps that the specified controller parameters of a specified controller are acquired; the specified controller is composed of a plurality of controllers acquired from a preset cooperative control model and connected in parallel; according to the specified controller parameters, an optimization result of the specified controller parameters is acquired based on a sphere artificial immune algorithm, and the device executes the above method. According to the optimization method and device for the specified controller parameters, the optimization result of the specified controller parameters is acquired based on the sphere artificial immune algorithm, the calculated amount during the operation process can be reduced, so that the algorithm is provided with the global search capacity, and the control effect is effectively improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of optimization control, and in particular to a method and device for optimizing specified controller parameters. Background technique [0002] In complex industrial control systems, such as power control systems, there are many types of damping controllers, and various controllers will have different effects on the damping of the entire system. If the controller parameters are not coordinated properly, it will not only fail to improve the system Damping, on the contrary, may worsen the damping of the system, so the coordinated control among multiple controllers has become a research hotspot. The common multi-controller coordination design idea is to coordinate the parameters of multiple controllers at the same time, such as genetic algorithm, particle swarm Algorithm, linear optimization algorithm, chaos optimization algorithm, simulated annealing algorithm, etc. [0003] In the p...
