Constraint characteristics in dual loop ADRC EMA servo. (IMAGE)
Caption
The method involves changing the triple-loop cascade control to a dual-loop control architecture with an integrated outer loop for position and speed control and an inner loop for current control. Meanwhile, aviation electro-mechanical actuation systems face various nonlinear constraints, such as voltage, current, mechanical stress, power supply characteristics, and heat dissipation. It is necessary to achieve performance optimization through nonlinear ADRC.
