[0002] The embedded servo vibration cylinder controller is a micro electronic controller specially used to control the vibration cylinder. Due to its fast response speed, low network dependence, small size and easy deployment, it has gradually been widely used in the field of industrial vibration control. In actual use, the controller needs to connect multiple signals, including control signals, feedback signals, actuator signals and sensor signals, among which many signals exist in the form of analog quantities. For example, the pressure in the cylinder collected by the pressure sensor and the cylinder temperature collected by the temperature sensor are usually expressed as analog current signals, while the vibration signal feedback is usually presented as an acceleration signal in the form of analog voltage. Due to the inherent errors in the embedded hardware circuit itself, there will be deviations between the actual measured value and the output value. In order to ensure that the controller can be accurately controlled during use, all analog input and output channels must be calibrated in the production test link.
