变频调速系统将压力作为控制对象,压力变送器将储气罐的压力转变为电信号送给变频器内部的PID调节器,与压力给定值进行比较,并根据差值的大小按既定的PID控制模式进行运算,产生控制信号去控制变频器的输出电压和逆变频率,调整电动机的转速,从而使实际压力始终维持在给定压力.

Frequency control system pressure as the control object, the pressure tank pressure transmitter will be transformed into electrical signals sent to drive the internal PID regulator, and pressure for a given value for comparison, and according to the size difference between the established The PID control mode for operation, control signal to control the inverter output voltage and inverter frequency, adjust the motor speed, so that the actual pressure was maintained at a given pressure.
