TL;DR: In this paper, a control system for a bi-fuel engine with a powertrain controller and a Bi-fuel controller is described. But, the control system is limited to a single driver and each of the drivers can be used to generate a corresponding control signal for either a gasoline fuel injector 38 or an alternate fuel (AF), respectively.
Abstract: A control system 14 for a bi-fuel engine 12 Is provided. The control system 14 includes a powertrain controller 52 and a bi-fuel controller 54. The controller 52 has a set of fuel injector drivers 92. The controller 50 has a set of gasoline fuel injector drivers 104 and a set of alternate fuel (AF) fuel injector drivers 106. Each of drivers 92 in controller 52 is electrically connected to a driver 104 and a driver 106 in controller 50. Thus, a control signal generatea by a single driver 92 can be utilized by either of drivers 104, 106 to generate a corresponding control signal for controlling a gasoline fuel injector 38 or a AF fuel injector 40, respectively.

TL;DR: Experimental results show that a controller designed for the reduced-order model guarantees effective vibration control of the flexible beam.
Abstract: A single-link flexible beam is an infinite-dimensional system. A full-order model containing all the modes of the system within the bandwidth of the actuator and sensors is presented. Such a model would result in a high-order controller which may not be feasible to implement in practice. Hence, a low-order model for the system is obtained using Hankel norm minimization. A controller is designed for the beam on the basis of the reduced-order model thus obtained. Experimental results show that a controller designed for the reduced-order model guarantees effective vibration control of the flexible beam. >

TL;DR: In both step response and tracking experiments the self-organising controller was found to perform better than a conventional PID controller under similar circumstances, although some tuning was required for the former system.
Abstract: The paper reports results of the practical application of the self-organising controller to the simultaneous control of two interacting joints of a robot. The rationale for its use and the architecture of this heuristic fuzzy rule-based dynamic control approach are outlined. This shows it to be a relatively simple intelligent knowledge-based system capable of both learning and displaying a variable nonlinear input/output relationship. In both step response and tracking experiments the self-organising controller was found to perform better than a conventional PID controller under similar circumstances, although some tuning was required for the former system.

TL;DR: In this paper, a baseband processor, a medium access controller and a base-band-media interface are provided with a input/output controller as an integrated circuit, where the printed circuit board may be a system board or a peripheral card.
Abstract: Apparatus for a baseband-media interface is described. More particularly, in an embodiment, a baseband processor, a medium access controller and a baseband-media interface are provided with a input/output controller as an integrated circuit. In another instance, a baseband processor, a medium access controller and a baseband-media interface are provided on a printed circuit board and coupled to an input/output controller via a bus. The printed circuit board may be a system board or a peripheral card.

TL;DR: A dead-time compensator and a model-following controller are proposed to enhance the robustness of the two-degree-of-freedom speed controller to improve the performance of the closed-loop controlled plant.
Abstract: A speed controller that considers the effects of system dead time and parameter variations is presented. An indirect field-oriented induction motor drive is implemented, and its dynamic model is found, using a stochastic approach. A two-degree-of-freedom speed controller is designed to match the prescribed speed command tracking and load regulating specifications. Since the performance of the closed-loop controlled plant is greatly influenced by the presence of the inherent system dead time and parameter variations during wide-range operations, a dead-time compensator and a model-following controller are proposed to enhance the robustness of the two-degree-of-freedom speed controller. The simulated and experimental results show that good control performance both in speed command tracking and load regulating characteristics is achieved. >
