本机具有自动跟踪随机取样反馈控制系统。用数字电路控制步进电机,步进电机带动水门开关实现自动控制。步进电机的角位移总量严格等于输入脉冲数,晶体振荡器频率精度和稳定精度均在10~(-6)以上,因此步进精度很高,发动机的转速可控制在±0.2%。
This machine has automatic tracking random sampling feedback control system. Digital circuit control stepper motor, stepper motor driven water gate switch to achieve automatic control. The total amount of angular displacement of the stepping motor is strictly equal to the number of input pulses. The crystal oscillator frequency accuracy and the stability accuracy are both above 10 -6, so the stepping precision is high and the engine speed can be controlled within ± 0.2%.
