In recent years, the research on Smith predictive compensation controller has become a trend. It can effectively compensate the delay of time-delay system, but it requires that the system has accurate control model and control accuracy is not high. At present, many researchers at home and abroad optimize the structure of Smith Predictive Compensation Controller,

Controller is the core module of ASP. NET MVC. It is the regulator between view and model, which embodies the business logic of application program. By introducing the method of ASP.NET MVC controller creating custom controller through IController interface and facilitating built-in controller by inheriting Controller class, this paper elaborates respectively from request receiving input

The remote control of aircraft model refers to the use of radio waves to transmit the operator’s command model to the rocker, thus instructing the aircraft model to make various flight postures. This paper mainly introduces the design of an aeromodelling remote controller based on ARM chip, and gives the circuit design and software design

This paper introduces arc extinguishing and overvoltage protection device (XHG). When arc grounding occurs, the device can make fault phase grounding through a group of vacuum contactors which can be controlled separately, so as to eliminate arc completely. The controller detects the fault phase through PT transformer, and then sends out control signal to the

Traditional methods mostly realize load shunting of communication system through specific hardware, but the scalability and sensitivity of hardware products restrict the quality of load shunting, and the system is in danger of load imbalance. Therefore, in order to improve the load balance of electronic communication system, a shunt controller of electronic communication system is

In bad environment, the speed sensor in power transmission system will fail, which results in low switching frequency limitation in low speed operation. At this time, the traditional direct torque control system is used to search the optimal motor parameter control point from a single point, and there is a high torque ripple. Therefore, a

In this paper, a multi-functional flower sensor is designed to detect and feedback the growth environment of flowers. The system can select flower types by keys, collect soil moisture information, temperature information and light intensity information in the process of flower growth through multiple sensors, and process data by Beetle microcontroller. Finally, the state is

The temperature controller based on PID regulation is widely used in modern temperature measurement system. This technology has the advantages of simple implementation and eliminating steady-state error. However, most of these instruments in the market use analog PID controller to control temperature, thermostatic element and using computer software to realize PID control algorithm has greater

In order to quickly judge the faults of solar street lamp system and verify the rationality of its system design, a controller with state data acquisition and storage function is designed. Supporting software monitoring platform based on WINDOWS operating system, through the PC to achieve internal data access and download, to achieve intelligent management of

RGB color mode is a color standard in industry. It obtains all kinds of colors by changing the three color channels of red (R), green (G) and blue (B) and their superposition. RGB is one of the most widely used color systems. However, most of the RGB controllers in the market are high-end controllers, which
