The use of mechanical thermostat in refrigerators presents more and more disadvantages, such as temperature drift, large error, no shutdown, no starting up, and so on, resulting in a large number of customer complaints and after-sales maintenance. From a low cost point of view, a computer controller based on single chip microcomputer is introduced to

With the continuous development of network technology and communication technology, as well as the continuous improvement of people’s living requirements, the realization of home intelligent remote control has become an inevitable trend. People are gradually pursuing the intellectualization and modernization of family life. People want to know the use of household electrical appliances at any

The development of social economy promotes the improvement of people’s living standards. People put forward certain requirements for the control accuracy and safety of tax-controlled fuel tanker controller. To a certain extent, the use of FPGA in tax-controlled fuel tanker controller can facilitate the research of tax-controlled fuel tanker. The application of FPGA controller in

PID control has the advantages of simple algorithm, easy design and reliable control. It is still widely used in various industrial control systems. However, with the widespread existence of the complexity, non-linearity and time-varying of controlled objects, the effect of conventional PID control is greatly reduced. Nowadays, various advanced control strategies are gradually introduced into

Load identification is a detection technology of safe power consumption in power management system. In order to alleviate the labor of managers, this paper presents a controller for identifying user’s load type. The hardware circuit and software system of this controller are introduced systematically. Through practical testing, it is found that this controller can identify

A water cooling system of passenger car motor and its controller can solve the cooling problem of passenger car and its controller very well. Because the working efficiency of passenger cars and their controllers is generally given by each manufacturer, and then the flow resistance and energy loss of water cooling system are analyzed, so

Aiming at the problem that controller parameters are not easy to be selected in industrial process control, a method for calculating controller parameters based on fractional order transfer function is proposed. A fractional order transfer function is set as the objective, and the form and parameters of fractional order controller are obtained by calculation. This

This paper puts forward the design concept of low cost and mechanical Underground Multi-storey garage. The whole frame structure and control system of the underground multi-storey garage is based on the design concept of low cost and low energy consumption. The MCS-51 microcontroller is used as the processor of the automatic control system of the

A new type of solar power generation controller based on embedded system chip EP4C15F17C8 is introduced in this paper. The overall design process of the controller is described, the charge and discharge circuit is analyzed in detail, and the performance indicators of the controller are given. The results show that the controller has the characteristics

With the rapid development of economy and society, the existing electrical control technology has been far from meeting the needs of actual production and life. In this paper, aiming at its own problems of poor safety performance, difficult to change and spread, the programmable logic controller is applied to achieve the goal of Mechatronics in
