Abstract

The invention discloses a corn harvester loss rate control method and device, a storage medium and equipment. The method comprises the following steps: constructing a dual-input single-output fuzzy neural network controller which comprises a front part network and a rear part network; carrying out offline learning by adopting a genetic algorithm-particle swarm algorithm, and determining a weight, a membership function center and a width which need to be learned in the fuzzy neural network controller by learning prior operation data of a system; carrying out online learning by adopting a BP algorithm, establishing the connection weight of the controller, detecting the rotating speed of the corn harvester kernel recovery device in real time, and adjusting adjustable parameters in the controller in real time in combination with online learning, so that the controller adapts to mechanical property changes of the corn harvester kernel recovery device and tracks a corn harvest rate set value. The invention further provides a corresponding corn harvester loss rate control method and device, a storage medium and equipment.

Description

technical field [0001] The invention relates to a corn harvester grain loss control technology, in particular to a method, device, storage medium and terminal computer equipment for controlling the loss rate of a corn harvester based on a fuzzy neural network algorithm. Background technique [0002] The corn harvester system is a complex control object with nonlinear, large time-delay, strong coupling and time-varying characteristics, and is disturbed by many uncertain factors, such as natural environment changes, mechanical wear, motor speed or human factors, etc. , these factors will cause the loss of corn harvest. Among them, the motor speed can be optimized by algorithm, so as to reduce the loss of corn harvest. [0003] Intelligent control has the ability of self-learning and self-adaptation, and has good control effects on linear and nonlinear systems, and can well solve the control of complex systems such as corn harvesters. Among them, neural network and fuzzy cont...
