Abstract

The embodiments of the invention disclose a bulb tube voltage control method and device, and a computer readable storage medium. In the single-time exposure process of a high-voltage generator, through a fuzzy PID algorithm, tube voltage output values sampled by an FPGA chip are calculated to obtain the voltage error and the voltage error changing amount; fuzzy reasoning and ambiguity resolving are conducted to determine the PID parameter increment, and set PID parameters determined by the PID parameter increment are calculated through an incremental PID algorithm to obtain the pulse width increment of PFM waves; and then the frequency of the PFM waves is adjusted through the pulse width increment, and the bulb tube voltage of a high-voltage oil tank is controlled to be adjusted in an adaption mode. The PID parameters are set in a self-adaption mode in real time through the fuzzy PID algorithm, it can be effectively guaranteed that the high-voltage generator conducts optimal output atthe whole exposure time, and the robustness of the set PID parameters and the efficiency of PID parameter setting are improved.

technical field [0001] The present invention relates to the field of digital technology, in particular to a ball tube voltage control method, device and computer-readable storage medium. Background technique [0002] In the high-voltage generator control system, the bulb voltage (both expressed in kV below) and the bulb current (both expressed in mA below) are the two most important technical indicators of the system, and the rising time of kV, overshoot, and ripple The size of the wave needs to meet the accuracy requirements in the national standard. With the current higher and higher requirements for the output power of the high-voltage generator, the exposure time is getting shorter and shorter, and the control of the kV of the high-voltage generator also requires higher requirements. [0003] At present, the commonly used kV control technology is digital PID control technology. Digital PID control technology performs PID parameter setting for each group of exposure para...
