	Power control -- Facts, Info, and Encyclopedia article (Site not responding. Last check: 2007-10-29)
		(Electric) Power Control deals with routing electric power, controlling its quality, and controlling the devices attached to a power line.
		A number of technologies have evolved for using the power wiring to turn devices attached to the power line on and off, monitoring attached devices, and similar activities.
		A collective term for one set of technologies is smart buildings.

	UMTS Power Control
		Open loop power control is the ability of the UE transmitter to sets its output power to a specific value.
		Outer loop power control is used to maintain the quality of communication at the level of bearer service quality requirement, while using as low power as possible.
		Power control of the downlink common channels are determined by the network.

	Power-Control
		Power is the attitude of strength, ``one up,'' ``on top,'' ``number one,'' or ``leader'' projected to others in order to direct how they live their lives.
		Control is the attitude of being strong, being on top of it, being in control, being self-led that one feels inside as he lives his life in his self-directed way.
		Power is often exerted by people who believe they have the ``answers'' but lack the patience for others in their lives to come a to consensus or agreement on what an appropriate course of action should be.

	Power Control
		By high power, we are referring to currents of 100 - 5000 amps, and voltages of 450V - to 27,000V.
		A solid state controller can let you run the same motor at varied speeds, increasing the life expectancy of the motor and the efficiency of the system the motor is in.
		To handle the required power levels, the components would have to be combined in series and in parallel.

	Control and Power 1993/4 (Site not responding. Last check: 2007-10-29)
		Other research activities include robust parameter estimation and control of systems with disturbances, saturation, and modelling uncertainties, intelligent controllers for industrial processes using neural networks, improvement of the dynamic stability of large-scale electrical power systems, variable speed drives for industrial electric motors, cost-effective management of energy demand, and mitigation of harmonic 'pollution' in power systems.
		We are continuing to investigate adaptive control schemes employing feedforward compensation that may be implemented in radio-telescopes for star tracking and satellite tracking applications for both small and large antenna structures.
		The robustness results obtained are for adaptive control of plants in the presence of deterministic disturbances, bounded disturbances, unmodelled dynamics, input saturation constraints, on-line computation constraints and their combinations.

	Power and Control - by M. Simon - Sierra Times.com
		Power is measured in watts or kilowatts, which is a thousand watts, very roughly one horsepower.
		Control theory tells us that in a control system if there is more than a one quarter cycle delay between the control output and the controlled element the system will not be controllable.
		So the power is surging back and forth in the system faster than the system can respond and there is not enough positive resistance load to absorb the transients.
