TL;DR: The position control of a pneumatic levitation system uses visual feedback to compute the object position, which can be modified by means of an air blower acted by a variable-speed drive.
Abstract: The position control of a pneumatic levitation system is described in this paper The control system uses visual feedback to compute the object position, which can be modified by means of an air blower acted by a variable-speed drive The system is employed as a test bed of control strategies A performance comparison attained by a classical PID, a robust Hinfin control law and a fuzzy controller is carried out, including tracking and disturbance rejection experiments

TL;DR: A discrete-time proportional integral derivative controller, the manipulated variable of which takes two values, i.e., ON and OFF, is proposed and analyzed and a cascade type and a built-in type are proposed.
Abstract: A discrete-time proportional integral derivative (PID) controller, the manipulated variable of which takes two values, i.e., ON and OFF, is proposed and analyzed. Oversampling technology is employed in the controller design. As to the structure of the controller, a cascade type and a built-in type are proposed. An experimental example is presented.

TL;DR: In this paper, the performance comparison of two different controllers for wind turbine yaw control is presented, which are a classical proportional-derivative (PD) controller and a fuzzy logic controller (FLC).
Abstract: This paper presents the performance comparison of two different controllers for wind turbine yaw control The two controllers evaluated are a classical proportional-derivative (PD) controller and a fuzzy logic controller (FLC) The controllers were separately used to operate the teetered rotor wind turbine presently being commissioned at the University of Texas at El Paso Without an adequate dynamics model, the performance of the PD controller is not sufficient to ensure proper response in the steady state In addition, the tuning process for selecting the optimum gains of the PD controller is an ad-hoc procedure depending on the wind condition In contrast, the nonlinear nature of the FLC provides superior response to the control requirements regardless of the wind condition Field experience gained from this experiment gives adequate confidence to apply the FLC for wind turbine yaw control

01 Jul 1974TL;DR: In this paper, a head controlled mechanism for the proportional control of a driven devi was proposed, whereby a control signal is generated proportional to the movement of the head of an operator to control the speed and direction of the driven device.
