Abstract

The invention provides a fuzzy control method for adjusting fire grate velocity and a controller and a control system thereof. The fuzzy control method comprises the steps that detection input quantity transmitted by a detection device is received; the deviation between the detection input quantity and a set value and the change rate of the deviation are calculated to act as the input variables of fuzzy control; and fuzzy reasoning and decision making are performed based on the input variables of fuzzy control so as to obtain fuzzy output quantity and defuzzify the fuzzy output quantity into output variables of fuzzy control, wherein the input variables of fuzzy control include the deviation between the detection input quantity of the feeding fire grate movement velocity and the set value, and the output variables of fuzzy control include the burning fire grate movement velocity. According to the method, the human brain can be more accurately simulated to process fuzzy information, the method is more artificially intelligent, the degree of automation can be enhanced, the efficiency of the burning fire grate can be enhanced, waste burning is enabled to be further sufficient and ash falling is further timely.

Description

technical field [0001] The present invention relates to the field of waste incineration, in particular to a fuzzy control method for adjusting the speed of a fire grate, a controller and a control system, and in particular to a fuzzy control method and a controller for adjusting the motion speed of an incineration fire grate for an incinerator and control system. Background technique [0002] The reduction, harmlessness, and recycling of domestic waste are major environmental problems at present and in the future. The technology of domestic waste incineration and power generation can significantly reduce the amount of domestic waste, and at the same time, it can use waste heat to generate electricity and realize resource utilization. In addition, it can control the secondary pollution to the environment, and has developed rapidly in our country. [0003] Garbage enters the incineration grate through the feeding system. The incineration grate is the incineration equipment fo...
