With the widespread use of BLDCM, the competition of controller market is becoming more and more fierce, and the contradiction between excellent performance and low cost is becoming increasingly prominent. In the hardware part, 79F9211 MCU is used as the controller, IGBT driving circuit and other auxiliary circuits are designed, and a three-phase brushless DC

The siphon time regulation controller is a device which can automatically adjust the hydraulic pressure in surge valve by adjusting the inflow flow of float chamber and the drainage flow of siphon pipe to achieve intermittent siphon time drainage. According to the characteristics of the self-made surge valve and the need of irrigation, the mathematical

With the progress of the times and the rapid development of science and technology, more and more technological means begin to be gradually combined with production work. This way of combination has greatly increased the production efficiency of enterprises, but also saved the production cost of enterprises to a certain extent. It plays a very

Nowadays, with the increasing shortage of energy, energy conservation has become a consensus. Air-conditioning is widely used in the real world. Single-chip computer is used to control the controller of electric air-conditioning compressor in order to control power consumption and achieve the purpose of energy saving. In this paper, starting from the background of using

The dynamic model of active suspension of monorail vehicle is established based on Darumbell’s principle. The LQG controller of active suspension of monorail vehicle is designed by applying stochastic linear optimal control theory and taking ride comfort and grounding as comprehensive evaluation indexes. The objective function including vertical acceleration of vehicle body, dynamic travel of

Integrative teaching is to organize and integrate teaching links, take the teaching of combining theory with practice to train students’vocational ability as a whole, aiming at improving the comprehensive quality of the educated, and adopt the method of combining theory teaching with practice. Often a teacher or a group of teachers jointly formulate the teaching

Installation art is a non-traditional art, which can interact with the surrounding environment. Arduino has an important application and great advantage in its development process. Arduino is an open source electronic prototype platform, including hardware and software. It can sense the state of the surrounding environment through a variety of sensors, and then use software

This educational reform takes the overall improvement of students’comprehensive design ability of electrical control system as the main line and aims at training the electrical technical talents urgently needed in society. It has carried out comprehensive teaching reform and exploration in classroom teaching, experimental teaching, network course construction, teaching materials and teaching team construction, and

Reza Electronics announced the launch of the RL78/F15 family of low-power 16-bit microcontrollers for the body control module (BCM), air conditioning, electric seats and other automotive control systems. As a sub-series of RL78 series micro-control, RL78/F15 products achieve industry-leading CAN communication with low power consumption, high performance and independent control and diagnosis. 　　The products are

Modern radar servo systems mostly use PID control, while traditional PID control has some limitations under the non-linear system, time-varying system and large inertial system. Aiming at the complex mathematical model of radar servo system, a method of designing a fuzzy PID controller based on radial basis function neural network improved by genetic algorithm is
