AI Technical Summary
In time-delay systems, traditional extended state observer designs fail to effectively utilize model information, resulting in decreased observation accuracy, insufficient system anti-interference capability, and difficulty in tuning high-performance controller parameters, which affects the dynamic response performance and stability of the system.
By combining linear quadratic optimal control with model information-assisted linear extended state observer method, and by improving the extended state observer and dominant pole placement technique, the parameters of high-mode PID controller in the time-delay system are tuned to achieve accurate estimation and compensation of disturbances.
It improves the system's dynamic response performance and anti-interference capability, enables faster reference signal tracking and steady-state error elimination, enhances the system's tracking accuracy and settling time, and significantly improves the system's anti-interference capability.
