[Abstract]:The development and maturity of computer technology, microelectronics technology and communication technology promote the development of measurement and control technology towards the direction of intelligence and networking. At the same time. Various application fields for the instrument control effect and overall performance requirements continue to improve, so that the functions of measurement and control instruments tend to improve, the performance of a large improvement. In the past few decades. All kinds of testing and control instruments have undergone many innovations and have been continuously playing an important role in practical application. As a universal control instrument, loop controller has emerged as the times require and has been widely used in temperature. In control situations such as pressure, its performance plays an important role in the overall performance of the measurement and control system. However, the traditional loop controller has shortcomings in the performance of control algorithm, man-machine interaction and the completeness of data communication. It is of practical significance and application prospect to study the new high performance loop controller. Based on the introduction of the development history and research status of the loop controller, the development trend of the new loop controller is analyzed with the help of relevant simulation tools. In this paper, the conventional PID control algorithm of the loop controller is studied, and the fuzzy intelligent control theory is combined. A parameter adaptive fuzzy PID algorithm is presented.
