This topic is in the biomass integrated multiple flash pyrolysis liquefaction production of bio- fuel technology \measure the temperature of the heat carrier in the reactor by fuzzy adaptive PID control method and its constant temperature control , flow measurement and control of the weighing method and the open -loop stepper motor control . PID control is one of the earliest developed control strategy , its simple structure , robustness , high reliability , and are widely used in industrial control process , in particular, was able to build accurate mathematical model of deterministic control system . Fuzzy control is not sensitive to changes in the parameters of the controlled object , has a strong robustness and fast response , able to overcome the nonlinear factors , etc. , in the industrial process control is widely used . Combination of fuzzy control and PID control , both accurate PID control and fuzzy control flexibility and control for nonlinear , time-varying control objects . In this paper, the heat carrier furnace controlled object to combine the advantages of the PID control and fuzzy control , MATLAB software targeted at first-order inertial lags digital PID control , fuzzy control and fuzzy control adaptive PID control performance and anti-interference ability simulation , simulation results show that the parameter fuzzy self- tuning PID control to meet the regulation time , small overshoot and steady-state error small control requirements , strong interference suppression , the papers are finalized the fuzzy adaptive PID control programs . Based on TI's TMS320F2407 design temperature and flow measurement and control systems , including fuzzy adaptive PID controllers , sensors, straw gas flow control electric valve , stepper motors and some peripheral devices , details fuzzy temperature controller hardware and software design . Controller TI's TMS320F2407 collected for the control of the core temperature measurement circuit output voltage , fuzzy adaptive control algorithm ; stepper motor driven ball screw flow control valve to complete the requirements of this topic .
