CNC machine tools are commonly used in the production process, but the high cost of CNC machine tools often restricts the progress and development of production.In order to enrich the functions of existing CNC machine tools in China, this study explores the important technical problems of low-cost transformation of CNC machine tools by using open

This design takes STC89C52RC single chip computer as the control core, adjusts the motor speed by keys, then transmits the speed control instruction to STC89C52RC single chip computer for processing, and displays the theoretical value of DC motor speed through LCD1602 display, then processes it by STC89C52RC minimum system, thermostatic element and inputs the signal

Nowadays, the single chip computer is occupying the dominant position of the intelligent control system at the speed of rapid speed. Various kinds of color lights are also accompanied by our life. The music color lamp controller is made by AT89C51 single chip computer. Because the frequency of the single chip computer is different, when

In order to study the influence of input delay on the stability of Timoshenko beam system, a new controller is designed to compensate for the influence of input delay by using Backstepping method to stabilize the Timoshenko beam system with input delay and load at the boundary, thus a stable closed-loop system is obtained. Firstly,

In view of the contradiction between the hardware conditions of the programmable controller training room and the relatively backward training assessment methods, a method of training assessment based on lottery software is proposed. Through students’feedback, the new practice assessment method has improved the credibility of the training results, improved the information level of the practice

Through introducing the characteristics and working principle of electromagnetic flowmeter and its application in oil field combined station, this paper puts forward that the advantages and disadvantages of flowmeter in measuring flow are mainly analyzed, and technical improvement is strengthened to make electromagnetic flowmeter work stably and measure accurately in combined station. In the daily

Multiphase permanent magnet synchronous motor (PMSM) has better performance than traditional motor. Its redundancy makes PMSM keep running after phase-out or phase-out. In this paper, a multi-phase permanent magnet synchronous motor controller based on TMS320F28335 is designed. The design method of minimum system and peripheral circuit of DSP is given. A 50W power supply is

With the rapid development of computer network technology application in Vocational colleges, it is self-evident that network services bring convenience to information-based campus, and efficient security management of data center servers is also essential. This paper mainly analyses the key technology of network migration on domain controller to prevent the serious impact of migration failure,

At present, the single motor wiper system commonly used in automobiles is synchronous swing of wiper arm through mechanical connection. This structure has some shortcomings, such as large space occupation and inconvenient maintenance in case of failure. The dual motor wiper system overcomes these shortcomings and reduces the weight and mechanical noise of the system,

With the wide application of AC motor in the field of electromechanical servo, the hardware design and implementation of an AC servo motor controller based on ARM are introduced. PWM signal generation and control, rotor position detection and speed control are realized by using advanced timer, SPI and QEP interface in the selected ARM processor.
