Abstract
In this paper, the author discussed the application and design of ceramic kiln control system based on PID. Ceramic kiln plays a very important role in the process, and the level of automation in kiln determines the development of the ceramic industry. The firing of ceramic kiln is a thermo technical process with the variation of time, large time delay and much interference. The temperature control system is the core of the whole ceramic kiln control system. In this paper, in order to improve a wide range of temperature control accuracy, by combining fuzzy and PID control methods a fuzzy PID temperature control system of the thermal analyzer based on ARM microprocessor is designed and implemented. In this paper, the hardware has been designed by using 32-bit ARM7 processor LPC2368 as the core. The system selected the temperature sensor of Platinum-Rhodium thermocouple. The zero-crossing detection opt coupler devices and TRIAC make up the implementation unit. Human-computer interaction interface composes of the key and LCD.
