A class of complex control system of the nonlinear , time-varying , large time delay , big inertia has been hot and difficult to control subjects . For more than a class of complex control system , the most advanced control algorithms so as to establish the mathematical model , based on the presence of the dynamic two issues dependence on the mathematical model of the controlled system structure and modeling . The actual uncertainty due to the production process and production apparatus , so that the phenomenon of advanced control model mismatch , the system is running a bad effect . Model-free adaptive control algorithm ( MEAC ) does not depend on modeling , using only the I / O data controller is designed , the MFAC applied to a complex system is a very meaningful work . In the batch type reactor in the chemical reaction process is the object of study, the the MFAC application in VCM polymerization process stage kettle temperature control thermostat to control its temperature within a predetermined range within . The VCM polymerization process and its mechanism is complex , highly nonlinear , time-varying , large inertia , and has a large heat capacity of the reactor , a larger delay the control object . Comprehensive research results of the previous reaction kinetics , heat transfer model for a particular reactor, process and product , comprehensive mathematical model of the polymerization process used to generate the I / O data . The text used by the model used to generate the input and output data only , without participating in the controller design . The main work of this paper is as follows: 1, using Matlab simulation to verify MFAC the effectiveness of complex object control system . Contrast control effect of the the tight format linearization ( TFL - MEAC ) and partial format linearization ( PFL - MEAC ) , in a complex system , partial format linearization control better control of linearization of tight format , and be construed accordingly. Research cascade MFAC larger disturbance of the single-loop the MFAC cascade MFAC control effect of cooling water temperature is compared by simulation , and gives the corresponding explanations . 3 , combined with previous studies the VCM polymerization kinetics model , the the VCM polymerization process heat transfer model built for a specific process and reactor , a comprehensive mathematical model of the polymerization process , the actual situation encountered in industrial production made simulation, the actual production of guiding significance .
