Impedance-compensated grid synchronisation for extending the stability range of weak grids with voltage source converters [PDF]
, 2016 This paper demonstrates how the range of stable power transfer in weak grids with voltage source converters (VSCs) can be extended by modifying the grid synchronisation mechanism of a conventional synchronous reference frame phase locked loop (PLL).

Impedance active control of flight control devices [PDF]
, 2010 The work presented in this paper concerns the active control of flight control devices (sleeves, yokes, side-sticks, rudder pedals,...). The objective is to replace conventional technologies by active technology to save weight and to feedback kinesthetic

Model Predictive Impedance Control [PDF]
2020 IEEE International Conference on Robotics and Automation (ICRA), 2020 Robots are more and more often designed in order to perform tasks in synergy with human operators. In this context, a current research focus for collaborative robotics lies in the design of high-performance control solutions, which ensure security in spite of unmodeled external forces.

Decentralized impedance control
IFAC Proceedings Volumes, 1994 Abstract We describe an impedance control method following an independent joint control approach. Simple impedance controllers are set up at each joint and coupling among the joints is cancelled using equally simple compensators. It is possible to program any diagonal visco-elastic impedance matrix in Cartesian task coordinates within the limits of ...

Design and control of parallel three phase voltage source Inverters in low voltage AC microgrid [PDF]
, 2017 Design and hierarchical control of three phase parallel Voltage Source Inverters are developed in this paper. The control scheme is based on synchronous reference frame and consists of primary and secondary control levels. The primary control consists of

Actuators, 2023 The integration of a passive elastic element in series between a motor and its load is popular in many human–robot interaction scenarios. By virtually imposing elastic behavior on the motor, an impedance control can act as a second stiffness to such an ...

Multiple-priority impedance control [PDF]
2011 IEEE International Conference on Robotics and Automation, 2011 Impedance control is well-suited to robot manipulation applications because it gives the designer a measure of control over how the manipulator to conforms to the environment. However, in the context of end-effector impedance control when the robot manipulator is redundant with respect to end-effector configuration, the question arises regarding how to

IEEE Access, 2019 The flexibility of the robot assembly process is critical, and a robot assembly system that is not flexible may damage the workpieces. Most researchers make the assembly process flexible by installing a six-dimensional force/torque sensor at the end of ...
