摘要： An OADM in a wavelength division multiplexing transmission system includes a wavelength selection switch that selects a predetermined wavelength from a multiple optical signal obtained by multiplexing a phase modulated signal and an intensity modulated signal and outputs the selected wavelength signal to a predetermined output port. The wavelength selection switch has a different delay for each wavelength of the multiple optical signal. For example, the wavelength selection switch includes a mirror array. Optical paths from the surfaces of mirrors arranged on the mirror array to the diffraction grating are different in the case of adjacent mirrors.

摘要： In an apparatus, a norm setter sets, based on a request torque for a rotary machine and a rotational velocity of a rotor, a norm of a vector of an a output voltage in a two-phase rotating coordinate system defined in the rotor. A phase setter sets, based on a deviation between a generated torque and the request torque, a phase of the vector of the output voltage of the power converter in the two-phase rotating coordinate system. A drive signal determiner determines, based on the norm set by the norm setter and the phase set by the phase setter, a drive signal, and applies the drive signal to a switching member to thereby drive the switching member such that the generated torque is adjusted to the request torque.
