  • Optimal control of coupled admittance controllers
    Patent number: 11400590
    Abstract: A coupling device (16, 116, 216, 316) configured optimally to communicate between a first and a second admittance controller and actuator assembly, the first and the second admittance control and actuator assembly respectively having a first and a second admittance controller (12a, 12b) configured to drive a respective first and a second actuator and each of the first and the second actuator being respectively connected to a first body having a first mass and a second body having a second mass, wherein the coupling device (16, 116, 216, 316) comprises: an input port having a first input for receiving a first input force signal (f1) from the first admittance controller and actuator assembly (12a) and a second input for receiving a second input force signal (f2) from the second admittance controller and actuator assembly (12b), and a processor adapted to derive a first output force signal for output to the first admittance controller and actuator assembly based on a Lagrange multiplier dependent on a comparison
    Type: Grant
