Abstract:
A motor controller includes: a velocity calculation unit for obtaining an angle θ(n), which shows a rotation position, and an angular velocity ω(n) of a rotor at a time point n; a compensation amount calculation unit for calculating a compensation angle Δθ by which the rotor advances from the time point n to a (n+1)th control cycle (a control cycle starting from a time point n+1), based on an angular acceleration a(n) of the rotor, an angular velocity ω(n) of the rotor at the time point n and a time length T of the control cycle; and a PWM inverter for controlling a voltage to be applied to a coil such that a rotating magnetic field based on a rotation position of the rotor advanced by the compensation angle Δθ from the rotation position of the rotor at the time point n is formed in the (n+1)th control cycle.

Claim (Index 12):
The motor controller according to  claim 1 , wherein\n the processor sets a target angular acceleration of the rotor according to a predetermined angular acceleration pattern showing a temporal change in the angular velocity, the voltage controller controls the voltage to be applied to the coil such that the angular acceleration of the rotor becomes closer to the target angular acceleration, and the processor obtains, as the angular acceleration of the rotor, an angular acceleration in a time period from the first time point to the second control cycle, the angular acceleration being shown by the predetermined angular acceleration pattern.
