Full-State Feedback Equivalent Controller for Active Damping in LCL-Filtered Grid-Connected Inverters Using a Reduced Number of Sensors
(Institute Of Electrical And Electronics Engineers, 2015-10)
This paper presents a method for the active damping of a grid-tie LCL inverter. This method is based solely on the feedback of the injected current into the grid, and is applicable to any linear current controller. It ...
On the controllers' design to stabilize ground resonance helicopter
(2019-12-01)
Ground resonance (GR) in helicopters is a potentially catastrophic instability commonly caused by coalescence of the regressive cyclic blade lag mode with the fuselage motion in certain rotor speed ranges. It can limit the ...
Fault Ride-Through Enhancement of DFIG-Based Wind Generation considering Unbalanced and Distorted Conditions
(Institute of Electrical and Electronics Engineers, 2012-09)
A control strategy is proposed to enhance the operation, under network disturbances, of a wind turbine driven doubly fed induction generator (DFIG). The scheme allows us to overcome low voltages, imbalances, and harmonic ...
Dynamic analysis of a new piezoelectric flextensional actuator using the J1-J4 optical interferometric method
(2005-12-01)
Piezoelectric actuators are widely used in positioning systems which demand high resolution such as scanning microscopy, fast mirror scanners, vibration cancellation, cell manipulation, etc. In this work a piezoelectric ...

Variable structure control of switched systems based on Lyapunov-Metzler-SPR systems
(2008-09-24)
This paper presents two Variable Structure Controllers (VSC) for continuous-time switched plants. It is assumed that the state vector is available for feedback. The proposed control system provides a switching rule and ...
