| Abstract: | Retort of chemical reaction (RCR) is very important and widely used in chemical industry. Here we present a simple and convenient way to control it, considering the common feature in many distinct production processes. The control of RCR is based on MCS-51 single chip microcomputer system, combining microelectronic, photoelectric and induction detection methods. We make use of time optimization, prediction, PID, and Bang-Bang control, to construct a mixed strategy. Control error and the rate of change of error decide which specific control method will work in time. Finally our intelligent RCR is realized by assembling language. |
