This paper presents the LQ-Servo control with observer for TCP/AQM system considering an input time-delay. This controller structure is made by taking a traditional servo mechanism based on Linear Quadratic approach and by augmenting a new state variable to the feed forward loop. In order to estimate the state of TCP window packet size, the control structure is extended with observer based on K...

The development of an automated bio-micromanipulation system provides high manipulation rates with optimal reproducibility and makes quantitative bio-micromanipulation possible. Visual-servo control is necessary for realizing automated bio-micromanipulation and increasing accuracy of micromanipulator. We have developed a dual-hand bio-micromanipulation system with micro-visual-servo control to ...

The paper aims to develop a novel pitch control system for a large wind turbine driven by a variable-speed pump-controlled hydraulic servo system. To perform practical pitch control experiments, a full-scale test rig of the hydraulic pitch control system for a 2 MW wind turbine’s blade, including a novel pitch control mechanism, a variable-speed pump-controlled hydraulic servo system, a disturb...
