20120103590 | FAN CONTROL SYSTEM AND AIR CONDITIONER THAT INCLUDES THE SAME - A fan control system includes a first fan, a second fan adjacent to the first fan, a first motor that rotates the first fan, a second motor that rotates the second fan, and a control unit. The control unit controls the rotational speeds of the first motor and the second motor. The control unit decreases the rotational speed of the first motor and increases/decreases the rotational speed of the second motor when the rotational speed of the first motor must be decreased, The control unit can decrease the rotational speed of the second motor when the rotational speed of the first motor whose rotational speed has been decreased is lower than a prescribed rotational speed, and increase the rotational speed of the second motor when the rotational speed of the first motor whose rotational speed has been decreased is higher than the prescribed rotational speed. | 05-03-2012 |
20140354198 | ACTUATOR CONTROL DEVICE - An actuator control device includes an upper-level control unit that sets an upper-level target value of a predetermined control factor relating to driving an actuator, a lower level control unit, and an intermediate control unit. The lower-level control unit has a command input element that receives an input of the upper-level target value and outputs a lower-level target value of the predetermined control factor, an actuator control element that receives an input of the lower-level target value and controls the actuator, and a tracking element that causes an actual value of the predetermined control factor in the actuator to track the lower-level target value. The intermediate control unit causes the actual value of the predetermined control factor in the actuator to track the upper-level target value. The upper-level target value is inputted into the command input element of the lower-level control unit via the intermediate control unit. | 12-04-2014 |
20150207447 | MOTOR DRIVE CONTROL DEVICE - A motor drive control device uses a rotor position sensorless control scheme to drive a motor. The motor drive control device includes a rotational speed deriving component, a startup component and a changing component. The rotational speed deriving component derives rotational speed of the motor just before startup of the motor. The startup component starts up the motor by outputting to the motor a drive signal based on at least one of a direct-current excitation scheme that fixes the rotor position in a predetermined position by performing direct-current energization, and a forced drive scheme that accelerates the motor to a predetermined rotational speed by performing forced energization that applies a predetermined voltage and frequency. The changing component changes the drive signal based on at least one of the direct-current excitation scheme and the forced drive scheme in accordance with the rotational speed of the motor derived. | 07-23-2015 |
