Vehicle air conditioner controllers mostly use traditional physical and mechanical keys. This paper mainly discusses the application of capacitive touch keys, another new type of keys, including the comparison of the advantages of touch keys and traditional keys, and introduces the structure and design considerations of capacitive touch keys, which can give follow-up capacitive touch

PI controller is based on TCP/AQM cybernetics model proposed by Mirsa et al. It uses control theory to study active queue management algorithm. In PI controller, the parameters are fixed and the performance is poor in high-speed network, which can not meet the design objectives of AQM. Therefore, an enhanced PI control algorithm, EPI, is

With the continuous development of society, the demand for high precision and high responsiveness of some automation equipment is increasing rapidly. 　　At present, the automation control technology is constantly improving, and some precise high-speed positioning control is guaranteed and widely used. Paper bag machine is a kind of equipment which forms multi-layer paper by uncoiling

This design is based on STC89C52 infrared remote control temperature and humidity controller. DHT11 digital temperature and humidity sensor is used to collect the temperature and humidity of the factory building. Through infrared receiving and processing module, temperature and humidity are set and adjusted directly. Digital tube display module is used to display the real-time

Bionic robots are electromechanical systems with excellent performance designed on the basis of bionics principles, imitating biological structure and motion characteristics. They have gradually shown good application prospects in complex mission environments such as anti-terrorism, explosion protection, space exploration, disaster relief and so on. At present, the problems of robot control system at home and

RF gain controller 11A9 of DF100A shortwave transmitter is prone to problems in operation, which directly affects the safe broadcasting. Firstly, this paper introduces the working characteristics, working principle and interface definition of automatic gain controller of 1A9, and then studies the scheme of adding equipment Part 1A9 for reference. Increase or decrease the RF

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.
