摘要：
This article designs a fuzzy logic controller that is applied to coal powder temperature control. As it is well known, many factors have influence upon control for constant coal powder temperature. Desiccant for coal powder-delivering system and coal powder-making system are hot air and cold air. Temperature of hot air can not be too high so that output temperature for coal-grinding machine or input temperature for coal powder-delivering machine are not beyond the controlled limitation. At the same time, if cold air is inputted too much, it will make coal powder temperature too low and the coal powder can not be burned completely. Ordinary PID controller can not control temperature well for both non-linear system with time change and system with unclear model. Fuzzy logic control can imitate people's thinking way. It can also use uncertainty and fuzzy information to make decision in order to realize successful control. 16-bit Lingyang single chip SPCE061A is applied as temperature-controlling chief unit to realize temperature control and temperature voice announcer function. Software design will apply fuzzy table-checking way to realize temperature control. The fuzzy control table will be obtained first by off-line calculation and then the control table will be saved in computer memory. It comes to conclusion that the fuzzy logic controller characterizes as simple structure, lower cost, readily realization, easily operation.
