Abstract

The invention relates to a compound control method for waste incineration. The control strategy of fuzzy control, traditional PID and open-loop control combined switch-shifting-type human thinking mode simulation is adopted, the error change rate adopts different control modes under a certain condition, meanwhile the load disturbance variable or the personnel empirical value is fed in through an open-loop mode, and the control precision is improved on the basis of ensuring stability. Fuzzy control adopts a two-dimensional control mode, the control rule uses the triangular membership function,and system dynamic performance is improved; incremental traditional PID adopts a canonical algorithm, and the system stability is improved; and disturbance control adopts an expert assessment weighting method to obtain the output quantity, direct loop opening acts on a control object, and the system response speed is increased. The intelligent-type control strategy integrating the various controlmodes and setting the criterion according to personnel experience for mode switching is adopted, and the good dynamic performance quality of control over a waste-incineration-type multi-parameter-object, nolinear and strongly-coupled system is achieved.

Description

technical field [0001] The invention relates to a compound control method for waste incineration. It belongs to the technical field of automatic control. Background technique [0002] Waste incineration is a waste treatment method with broad prospects. It is to fully burn waste through excess air under high temperature conditions, so that harmful substances can be oxidized and decomposed under high temperature, making waste harmless, reduced, and environmentally friendly. and regeneration. However, the composition of garbage is very complex, and its chemical structure and physical properties are not the same. In order to fully burn the garbage while reducing toxicity, the incineration process becomes very complicated. [0003] In order to ensure the operating efficiency of the waste incineration plant, the stability of the system is an important part, and the stability of the system requires a stable and efficient control method to ensure it. Waste incineration is a compl...
