A multi-axis leveling system synchronous control method based on real-time partial load observation adaptive compensation
By combining an extended observer and an adaptive law, the off-center load torque of the multi-axis leveling system is observed and updated in real time, solving the synchronous control problem of the system under high pressure and variable operating conditions, and improving the operational stability and accuracy of the composite material press.

AI Technical Summary
Existing multi-axis leveling systems are unable to cope in real time with dynamic and transient off-center load moments caused by mold asymmetry or uneven material distribution during composite material pressing under high pressure and variable operating conditions. Furthermore, they lack observation, estimation and parameter adaptation mechanisms for unmeasurable time-varying disturbances, leading to lag in control response or system instability.
An extended observer is used to observe the unknown time-varying eccentric load torque, and parameters are updated online through an adaptive law. A robust compensation term is constructed by combining the concept of backstepping control to achieve synchronous control of the multi-axis leveling system.
In composite material presses, the off-center load moment can be effectively observed and parameters updated online, achieving highly reliable disturbance rejection control and improving the system's operational stability and accuracy.
