The Optimization Research for the Control of Temperature on the SinglechipSystem Based on Particle Swarm Optimization

Abstract

According to the temperature measurement in the medical machine, the activity measurement of the biological tissue should be achieved in the same environment with living human system. Aiming at the applicational for the tempera- ture, a temperature controller based on the singlechip system is proposed to realize the measurement system. The modern control theory is used to analysis the controlling system which is based on the mathematic model and the state equation. The mehod that controlling the temperature be close to the target value and changing the parameter to reduce the error of the temperature is proposed which is based on the Particle Swarm Optimization (PSO). And the simulation results show that this method is adaptive with the temperature and the controlling way is feasilble. Then a singlechip system which is based on the chip PIC16C72A, is realized to slove the controlling problem. The experiments show that the scheme is equipped with accuracy and stability.
