power-on self-test การใช้

• This phase is often called power - on self - test ( post )
• Power - on self - test post
• The actuators are nozzle vetor controller , rotational measuring valve controller and vane controller . the smart actuators are capable of data collection , self - calibration , power - on self - test and local close - loop control , etc . a simplified mathematical model for the vector nozzle is constructed , and the relationship between the state of vector nozzle and actuator cylinders ’ position is obtained . the effect of the position controller is tested
