Greenhouse control research has been carried out for many years. On the one hand, the coupling problem of temperature and humidity is decoupled by a variety of algorithms. On the other hand, the coupling research of water and fertilizer is carried out for nutrients in greenhouse. In view of the problem of greenhouse system control,

The development of electric vehicles has been established as an important way to ensure energy security and transform the low-carbon economy by all countries in the world. According to Yole, a famous French consulting company, the production and sales of electric vehicles in the world will reach 20 million by 2020, and China has set

Programmable Logic Controller (PLC) is a compulsory course with strong practicality in automation specialty. Based on the Kunlun industrial control configuration software MCGS, this paper discusses the method of simulating the realization of PLC control object on the upper computer, and builds a course practice platform for the realization of PLC control system. Taking the

An intelligent control scheme for solar water heater’s functions such as inlet and outlet water, heating and leakage protection is designed and expounded. The purpose is to design a simple, high efficiency and low cost integrated device. This system uses STM32F103ZET6 of TI company as the main controller, and cooperates with temperature detection module, water

With the rapid development of national economy, a higher requirement is put forward for the dimension accuracy of thin plate. Because of the time lag in the thickness control system of rolling mill, the traditional PID regulation can no longer meet the technical requirements of thin plate. Smith predictor is used to compensate the measured

Firstly, the structure and working principle of FlexRay bus protocol and on-line control braking system are briefly introduced, and then Flexray is applied to on-line control braking system. By making full use of the advantages of Flexray communication, the source address allocation, output parameters and parameter group definition of each node of the on-line control

With the economic progress and the continuous development of science and technology, the research of asynchronous motor has attracted wide attention from all walks of life. Because of the adverse reaction of delay and overshoot in the vector system of asynchronous motor during the operation of traditional PI control mechanism, the relevant managers should upgrade

In order to speed up the intelligent and standardized management of rice seed soaking and germination promotion in Heilongjiang reclamation area, and improve the germination rate of rice seed soaking and germination promotion, a design method of fuzzy control was put forward based on Mitsubishi FX2N series PLC as the controller, aiming at the temperature

This system takes mcf52255 as the core processor, detects the signal of the traverse through the electromagnetic sensor, first processes the detected signal, obtains the road characteristic through the algorithm, then carries on the differential control and the steering control to the wheel through the PID algorithm, enables the intelligent vehicle to move along the
