Abstract


This paper is a building materials enterprise gesso block Chongqing productionline for the present situation of the background, Gesso block the production process ofthe characteristics and existing problems, Through the plaster block forming mechanismof various manufacturing processes of the analysis and optimization, combined with theactual production, aiming at the production control system controllable parameter isnumerous, can’t identify effective state estimate parameters to adapt to the productionline control system problems, and put forward based on reciprocating motion of gessoblock production line adaptive control system solutions, using the existing gesso blockmolding production for experimental platform, the design control hardware andsoftware system to enforce the project.Around the subject, this article mainly completed the following aspects of researchwork:①For plaster attribute, hydration mechanism needs analysis, analysis gesso blockproduction line production are the main difficulties, and based on the reciprocatingmotion of gesso block production line automation operation of the control systemframework.②The influence due to plaster block factors on the quality of the production andmore, according to the effect of each factor is different, in order to simplify the gessoblock in the production line of control parameters, the paper will be based on theorthogonal experiment modeling analysis system internal uncertainty related statefactors, according to the forming process and pulp flow analysis, choose a guarantorpress time, injection molding time, cleaning time, mixing time optimal statecombination of parameters.③Plaster powder is different, building gesso block the control model ofproduction line, sure gesso block production line control system of basic parameters,realize gesso block production line control system and external characteristics of theproduction line the adaptive optimization algorithm.④In the production line of gesso block due to equipment running status as theproduction status of change is the change, this paper based on the BP neural networktheory knowledge and the change of the system state parameters, build gesso blockproduction line neural network control model, and realize the state estimation based on the plaster block production line adaptive timing feedback adjustment of the algorithmdesign.This topic research is based on reciprocating motion of gesso block production lineadaptive control system was born to better solve the production of the mould happenedin jams, block molding products fault fault and so on, and ensure the stability of theproduct line, efficiency and quality. As application examples, this paper proposed basedon reciprocating motion of gesso block production line adaptive system has been inChongqing some building materials enterprise operation and achieved good effects ofoperation.
