Passivity and Passification for Networked Control Systems

SIAM Journal on Control and Optimization, 2007
This paper investigates the problems of passivity analysis and passification for network-based linear control systems. A new sampled-data model is first formulated based on the updating instants of the ZOH (zeroth order hold), where the physical plant and the controller are, respectively, in continuous time and discrete time.

A passive controlled hand rehabilitation instrument

Proceedings of the 2020 2nd International Conference on Big Data and Artificial Intelligence, 2020
The number of people with upper and lower limb disabilities is very large in our country. Many patients with upper and lower limb motor dysfunction due to various natural or man-made disasters, in addition to the use of traditional physical therapy in hospitals, also has applied in the rehabilitation treatment limb training to the rehabilitation robot ...

A sensorless passivity-based control for PMSM

2018 International Conference on Electronics, Communications and Computers (CONIELECOMP), 2018
This paper presents a sensorless controller design to speed tracking problem for a Permanent Magnet Synchronous Motor (PMSM). The technique of passivity requires knowing the load torque, this is estimated with a reduced-order extended state observer, a traditional reduced-order observer and an online algebraic estimator.

Design and Control of a Passively Morphing Quadcopter

2019 International Conference on Robotics and Automation (ICRA), 2019
This paper presents a novel quadcopter design that uses passive rotary joints to enable rapid aerial morphing without the use of additional actuators. The normally rigid connections between the arms of the quadcopter and the central body are replaced by sprung hinges that allow for the arms of the quadcopter to fold downward when low thrusts are ...

Control of cooperative manipulators with passive joints

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002
The problem of the control of cooperative manipulators with passive joints and are rigidly connected to a solid object is addressed in this paper. Passive joints can appear due to free-swinging joint failures or can be an intrinsic characteristic of the robots. A hybrid control of motion and squeeze force is proposed.

Passivity-based control of synchronous motors

2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe), 2012
Due to its great potential value in theory and application, nonlinear control strategies of synchronous motors (SM), especially passivity-based control (PBC) methods, have been a focus in the literature. A PBC strategy for SM with time-varying load torque to track flux and speed trajectories is proposed in this paper.

Control of convey-crane based on passivity

Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000
Based on the results of control of the inverted pendulum on a cart, we propose a control law of a convey-crane which transports a load suspended on a cart from a given point to another, minimizing its oscillations. The control law derived is based on the passivity property of the system. Some simulations are presented.

A passivation method for the design of switched controllers

2016 American Control Conference (ACC), 2016
We consider a feedback switched control system with non-passive subsystems. Introducing a passivation matrix, we transform each non-passive subsystem into a passive one and investigate the passivity of the resulting closed-loop system. The results are further extended to input feedforward passive (IFP) and output feedforward passive (OFP) switched ...
