Title:
ADAPTIVE FEEDBACK CONTROL OF FORCE FIGHTING IN HYBRID ACTUATION SYSTEMS
Document Type and Number:
Japanese Patent JP2019112044
Kind Code:
A
Abstract:
To provide systems for compensating for force fighting in multi-actuator systems.SOLUTION: A system 300 includes adaptive feedforward (FF) controllers 310 and 320, and optimal gain feedback regulators 312 and 322. The feedforward controller 310 and feedback regulator 312 operate to adjust operation of EHSA 110, while the feedforward controller 320 and feedback regulator 322 operate to adjust operation of EHA 120. A position command 330 is transmitted from a signal processor 302 to the feedforward controllers 310 and 320. Feedforward controllers work on local feedback compensators accounting for compensating against the difference forces between the actuators 110 and 120, which may be exasperated by noises, disturbances, and output loading. These feed forward controllers may synchronize the positions and output forces from each actuator.SELECTED DRAWING: Figure 3A
