摘要： The invention relates to an independent drive device for an aircraft, the drive device comprising a motor member, drive means for driving an aircraft wheel in rotation, which means are adapted to co-operate with said wheel to drive it in rotation, and coupling means interposed between the motor member and the drive means to selectively couple the wheel to the motor member, the coupling means comprising two coupling members of complementary shape, comprising a first coupling member constrained to rotate with the drive means and a second coupling member constrained to rotate with the motor member. The independent drive device includes measurement means for generating information representative of a relative speed of rotation of the second coupling member relative to the first coupling member, the device being associated with motor control means adapted to cause the motor to rotate so as to cancel the relative speed of rotation between the coupling members prior to coupling them together.

摘要： To drive a lens part by a servo motor, an automatic controller turns on the first switch to input a desired value to an error amplifier from a final controlling element, and turns off the second switch to activate a feedback circuit which performs negative feedback. On the other hand, if the desired value is 0, or if the final controlling element does not work, the automatic controller turns off the first switch to shut out the desired value from the final controlling element, and turns on the second switch to activate the feedback circuit which performs positive feedback. This enables hand operation of the lens part with support of the positive feedback.

摘要： A mobile body controlling gear is provided that can suppress an occurrence of yaw motion due to an offset when the P control is switched to the PID control. The yaw-axis control signal Ep is added to the control signal from the P/PID controller. The added signal is input to the actuator. The yaw-axis driving unit performs yaw-axis control. The yaw-axis angular velocity detection sensor signal Sa is compared with the reference signal r. Then the P/PID controller receives the comparison signal. The reference value memory holds the yaw-axis control signal Ep immediately before the P/PID switching unit switches the P control mode to the PID control mode. The yaw-axis control signal Ep is handled as the reference signal rb for the PID control. The reference value rb is added to the angular velocity zero detection reference value rz and to the yaw-axis control signal Ep. The resultant sum is input to the PID terminal of the P/PID switching unit. The error between the resultant sum and the yaw-axis angular velocity sensor output Sa is output as an error to the P/PID controller.

摘要： An adaptive airflow control system for positioning damper systems or controlling air units utilized in an environment control system is provided. The system is based on a fixed-gain, proportional-only feedback design to provide stable operation given the nonlinear behavior of flow through a valve or damper. A time-dependent deadzone of nonlinearity is used to reject measurement noise. The deadzone of nonlinearity is adjusted by an adaptively calculated proportionality constant which is capable of switching the control system between various operating modes for adjusting the performance of the system.
