Design and research for thermostatic controller based on PID control algorithm
In this paper,a thermostatic controller based on PID control algorithm is proposed,which meets the user's demand for a comfortable bathing experience and improves the intelligence and portability of the thermostatic bathtub.The acquisition,amplification,filtering and temperature closed-loop control of thermal conductivity signals of the closed-loop thermostatic controller are designed in this paper.According to the collected temperature data,the proportional,integral and derivative parameters are designed,the different value between the target temperature and the actual temperature is calculated,and the parameters of the thermostatic controller are adjusted to obtain the optimal heating mode.The experimental results show that the designed thermostatic controller can control the final temperature error at the range of±0.1℃,improve the heating efficiency of water temperature,and achieve more accurate temperature control effect.
