A control system for motors, generators and other electric machines that improves machine performance by dynamically adapting to changes. These changes may be in user inputs, machine operating conditions and/or machine operating parameters. The control system can take advantage of more independent machine parameters. That gives greater freedom to optimize and allows motors and generators to perform better than bigger, heavier machines, particularly more efficiently. The control system is software-based. So standard interfaces allow the control system to be improved and updated without changing hardware. This adaptive control system improves performance in a wide variety of motor and generator applications, particularly those that need high efficiency over varying conditions.

An object of the invention is to suppress degradation in image quality of a liquid crystal display device which performs display by field sequential method and to reduce power consumption of a backlight. The highest brightness of a first color light in a pixel region is detected. Gamma correction is performed so that transmittance of a pixel of the region displaying the highest brightness of the first color light is set to maximum and transmittance of other pixel of the region is decreased in accordance with lowering of the first color light intensity, and the region is irradiated with the highest brightness of the first color light. Similarly, a second color light is irradiated in another region concurrently with irradiation of the first color, whereby input of an image signal and lighting of the backlight are performed simultaneously in every region of the pixel portion.

This invention relates to control method and apparatus of wind machine for plant frost protection, and belongs to the domain of agro-meteorological disaster monitoring and control. Existing wind machines for plant frost protection only rely on critical damage temperature or wind speed as a condition to start. If there is no thermal inversion, operation of the wind machine will aggravate freezing injury to plants. If the strength of thermal inversion is weak, the effect will be minimal The feature of this invention is that when temperature at the plant canopy is lower than the critical damage temperature of a certain plant and temperature difference between the top and bottom of the thermal inversion layers exceeds set threshold, wind machine will start automatically. Otherwise it will remain off. The control apparatus mainly consists of sensor 5 at the top of thermal inversion layer, sensor 7 at bottom of thermal inversion layer, and controller 4. This invention of the control of frost protection wind machine ensures rational and effective operation and avoids aggravated freezing risk due to misuse of energy and incorrect operation.

By driving a fuel pump suitably to an amount of fuel according to an amount of fuel consumed by an engine and by monitoring an actual motor speed of the fuel pump, F/B control is carried out according to a target motor speed and the actual motor speed of the fuel pump. Meanwhile, by learning and storing a duty value comparable to a deviation between the target and actual motor speeds, duty driving of the fuel pump is corrected to suit an engine condition. It thus becomes possible to provide a fuel pump control apparatus of an engine capable of promoting power saving by suppressing a wasteful energy loss including a current consumption and making an internal circuit of an ECU simpler by enhancing fuel supply accuracy.
