Temperature control plays an important role in industrial production. In this paper, a temperature controller is designed based on self-tuning PID control algorithm. Finally, a simulation model is built by Simulink software to verify its correctness. Temperature is one of the most basic physical quantities in industrial production and life. The development of many disciplines

This paper introduces the elevator control system with PIC single chip computer as the core part. 　　The control system sends out the command signal by identifying the level change caused by the press of the key. The system processes the command signal and controls the elevator to operate accordingly. When the elevator fails, the system

With the development of digital technology of TV and audio, people’s demand for image and accompanying sound is getting higher and higher. In order to better meet the audience’s demand for high-quality programs, Guizhou Radio and TV Station has started the construction of Guizhou Satellite TV HD Channel technology project since 2010. On October 28,

The intake system of large warehouse is an important system for monitoring large warehouse of bulk carriers. The purpose of installing the detection and alarm device for intake of cargo hold on bulk carriers is to know the situation of accidental intake of cargo hold in time, so as to take corresponding measures in time

The structure and function of the independent servo controller are introduced, and a new method of the application of the independent servo controller in fatigue test is studied. Independent servo controller is a universal independent digital servo controller, which can operate independently without PC. Each rack can control up to four control channels. Most of

Precision detection circuit is adopted, which can detect the relative humidity of ambient air accurately, and send the measured data to the processor (AT89C51) after A/D conversion. Then the relative humidity of the current environment is converted to decimal digits through software programming, and then displayed by digital tube. Moreover, through software programming, coupled with

Because the traditional annealing furnace temperature controller is no longer suitable for the practical application of annealing furnace today, high-precision furnace temperature controller came into being at the historic moment. This kind of high precision furnace temperature controller includes improved PID controller, strip parameter corrector based on data table and fast heating, cooling regulator, gas

The PID controller is also called the PID regulator or the PID correction device. It mainly has the proportional control, the proportional differential control, the proportional integral control and the proportional integral differential control and so on. When the structure and control law of the PID controller are determined, it is very important to correctly

Intelligent robot controller for hydrothermal forming of hull panel is a modern control tool with high technical level and machine gun characteristics in ship production, which is particularly important for ship safety. 　　However, there is still a big gap in the research of this project in our country, which makes the existing research results relatively

Permanent magnet synchronous motor (PMSM) is a complex control system with non-linearity, time-varying and strong coupling. The conventional PID controller design method can not achieve good control quality (including stability, rapidity and robustness). Genetic algorithm is a kind of intelligent optimization algorithm, which has good global optimization ability, is not easy to fall into local
