Embodiment Construction
[0022] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. With regard to the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0023] At present, the level of industrial automation has become an important symbol to measure the level of modernization in various industries. At the same time, the development of control theory also experienced three stages: classical control theory, modern control theory and intelligent control theory. Typical examples of intelligent control are fuzzy fully automatic washing machines and so on. Control systems can be divided into open-loop control systems and close...

The present application provides a PID control method, device and video codec system, the PID control method includes: according to the difference between the output value of the proportional integral differential PID controller in the target control system and the theoretical value, determine the PID The current reward value corresponding to the PID parameter of the controller, the PID parameter includes at least one of proportional gain, integral gain and differential gain; in the case that the current reward value is less than 0, according to the current accumulated reward value and the This PID parameter is updated by the reward value this time, wherein the accumulated reward value is determined according to the reward value this time and the previous accumulated reward value; according to the updated PID parameter, the target control system The PID controller performs the next PID control. The method, device and system of the embodiments of the present application are beneficial to reducing the difficulty of setting PID parameters and improving the control performance and versatility of the PID controller.
Description
technical field [0001] The present application relates to the field of control, and more specifically, to a PID control method, device and video codec system. Background technique [0002] At present, proportional integral differential (PID) control is widely used in the field of control because of its simple algorithm and good reliability. The PID parameters of the traditional PID controller can include proportional gain, integral gain and differential gain. The PID parameters directly determine the control performance of the PID controller. Therefore, parameter tuning of PID controller is the core content of control system design. The traditional parameter tuning process relies heavily on the experience of relevant practitioners. By repeatedly debugging the PID parameters until they meet the actual application requirements, such adjustment workload is huge. Contents of the invention [0003] The present application provides a PID control method, device and video encod...
