基于MSP430F149单片机与模糊控制的温控仪设计

温度是科学技术中最基本的物理量之一，在工业生产和生活中，常常是表征对象和过程状态的重要参数，其控制具有非线性、时滞性和不确定性，用传统的控制达不到好的控制效果。设计一种以单片机MSP430F149为系统的核心部件，并将模糊控制算法应用到其中的温控仪上，温度控制范围为常温0～100℃，设定温度值与测量温度值实时显示，控制精度可达±0．5℃。该系统采用恒流供电，电路较简单，成本低，温度控制精度高，可以广泛应用于需要进行恒温控制的生产和生活中。

Design of Temperature Controller Based on MSP430F149 Microcontroller and Fuzzy Control

Temperature is one of the basic physical quantities in science and technology. In industrial production and life, it is an important parameter which often characterizes the state of objects and process. The traditional control for temperature can not achieve a good effect because of its nonlinear, time delay and uncertainty. A temperature controller, in which the fuzzy control algorithm is applied and MSP430F149 mieroeontroller is taken as a core component, is designed. Its temperature con- trol range is 0-100 ℃. Its temperature setting value and measured value are displayed in real-time. The temperature control accuracy is±0.5℃. The system uses constant current power supply. Its circuit is simple. Its cost is low. Its temperature control accuracy is high. It can be widely used in the production and life which need temperature control.
