The delay of the forward channel and the feedback channel is one of the main factors that affect the current loop control effect. However, a large amount of literature currently only pays attention to the forward channel delay, which has a great impact on the system, and ignores the influence of the feedback channel delay on the system. Based on the actual current loop model, the bandwidth and dynamic response of the servo control system when the forward channel delay and the feedback channel delay exist simultaneously are analyzed. Provide theoretical reference for engineering practice.
