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

ABSTRACT

According to the temperature measurement in the medical equipment, the activity measurement of the biological tissue should be achieved in the same environment with living human system. Aiming at the application for the temperature, a temperature controller based on the single-chip system is proposed to realize the measurement system. The modern control theory is used to analyze the controlling system which is based on the mathematic model and the state equation. The method that controls the temperature to 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 temperature and the controlling way is feasible. Then a single-chip system which is based on the chip PIC16C72A, is realized to solve the controlling problem. The experiments show that the scheme is equipped with accuracy and stability.
