In people’s daily life, the existence of elevators can not be ignored, their functions and functions are extremely important, especially in high-rise buildings. 　　In this paper, the author mainly from the basic structure of the control system and software design, analysis of the application strategy of programmable controller in elevator control system. At present, the

Reliability is a very important index for servo system. Reliability prediction is one of the important contents of reliability design. 　　In different stages of product design and development, reliability prediction in different depths is required. Focusing on the development of professional foundation, this paper describes the first time to use WQS10.0 reliability comprehensive analysis software

In this paper, an impulse controller is designed for distributed parameter systems with time-varying delays, and the stability of such systems is discussed. Based on Lyapunov stability theory, sufficient conditions for the existence of exponentially stable impulse controllers for distributed parameter systems with variable time delay are obtained. Finally, a numerical simulation is given to

In order to adapt to the diversified rural sewage control technology and improve the quality of rural sewage effluent, it is necessary to design a controller with high reliability and data upload. The design of rural sewage treatment controller first realizes reliable hardware circuit according to the requirements of process control and on-site use environment.

[Textbook Analysis] Electronic Technology Foundation and Skills is a core course of electrical specialty in secondary vocational schools. It takes the completion of electronic process as the main line, integrates the

PLC programmable controller is the mainstream of the development and application of electrical automation. Taking this as an example, this paper connects the adjustable water resistance step-down elements in series with the star-limited starting current of high voltage and large capacity three-phase asynchronous motor to realize smooth starting of motor. This paper also introduces the

Ocean buoy is the most widely used water temperature and meteorological monitoring equipment, which plays an important role in monitoring and harnessing the marine ecological environment. However, because the system needs 24 hours of uninterrupted work, the function problem has become the most critical factor restricting the further development and utilization of the system. Based

With the continuous development of the current economy and the continuous progress of social science and technology, people have accelerated the pace of a series of work on using new tools to replace human resources. Programmable controller is one of the tools. Programmable controllers (PLCs) are developing rapidly from R&D to today’s application and development.

Controller belongs to the brain of industrial robot. The quality of its design has a direct impact on the performance and accuracy of industrial robot. Six-axis industrial robots are one of the types of industrial robots. The complexity of motion control is relatively high. From the point of view of the existing motion controllers in

In recent years, with the continuous development of electrical control technology, the application of PLC is also increasingly widespread. The high performance of PLC controller makes it have strong adaptability and reliability, and it is widely used in the field of automation control. At the same time, because the cost of PLC is low and
