ABSTRACT
咖啡玉米Nowadays, automation control system has been widely in industries, and the application and development of electric control system of dc speed as the main method of transmission, in modern plays a main role in production. Along with the development of microelectronics technology, integrated chips in the governing system not only makes the application system, volume decreases, and reliability, and various classic and intelligent algorithm in the governing system of the flexible application, so as to achieve the optimal control.
This design from the working principle of dc motor are analyzed in detail, and the principle and system static and dynamic performance. Then according to the principle of the automatic control system of single loop, the design parameters of analysis and calculation, and also in dc speed control system based on the study of the theory of single closed loop speed regulator in the dc speed control system by PI control algorithm,, the speed closed loop dc speed control system is performance is very good, one of the most widely used dc speed control system, adopt 蝇蛆蛋白single closed loop speed dc speed control system can get good static and dynamic characteristics of speed. Speed si
ngle closed loop control dc speed control system, the characteristics and the design method of ac, dc power is dragging the automatic control system is the important foundation. In the design of TL494 adopted PWM control pulse width adjustment as the control circuit.
