Summary: | The utility model provides a servo pressure control system, includes servo pressure controller, pressure sensor, servo motor part, servo pressure controller includes MCU, ADC circuit, DAC circuit, analog input signal balancing circuit, analog signal PID regulator circuit, pressure sensor will reflect that the voltage signal of pressure value gives servo pressure controller, reflect that the voltage signal of user command gives servo pressure controller, and the voltage signal of reflection pressure value gives the ADC circuit after the analog signal zeroing circuit, do proportion, total mark, differential processing by the analog signal PID regulator circuit to two voltage signal's of reflection pressure and target pressure amount of dispersion, and gained voltage signal gives ADC circuit and voltage signal 0 system. Servo pressure controller still includes the analog signal amplitude limiting output circuit of voltage signal restriction within the certain limit with carrying. The utility model discloses pressure control's difficult point has been solved in automatic trade to real -time response and control accuracy have been increased substantially. |
