Moreover, the motion trajectory information can be reasonably distributed to each servo controller to ensure that each servo motor can perform telescopic motion according to the planned trajectory, thus realizing the efficient execution of complex motion tasks. By collecting the motion data of the motion platform in real time, the adaptive adjustment unit can dynamically adjust the control parameters of the servo motor. This adjustment mechanism can effectively cope with the dynamic changes during the motion process and improve the stability and adaptability of the system. The intelligent monitoring unit can collect the status of the servo motor and the motion range of the motion platform in real time, detect abnormalities or faults in a timely manner, thereby effectively avoiding shutdown or damage caused by faults.
