  • Patent number: 11821952
    Abstract: A method of estimating a d-q axis inductance of a permanent magnet synchronous motor includes the following steps. First, building an equivalent motor control block through enabling two of the three phases, and disabling the remaining one of the three phases, and locking a rotor. Afterward, incorporating a back EMF observer into a DC motor control block, and making the DC motor control block correspond to the back EMF observer by commanding an angular speed of the DC motor control block to be zero. Afterward, introducing the equivalent motor control block into the DC motor control block, and using the back EMF observer to estimate the back EMF, and repeating above steps taking turns to disable one phase so as to obtain three sets of motor inductances respectively. Finally, estimating the d-q axis inductance by introducing the three sets of equivalent motor inductances into an inductance relational equation.

  • Patent number: 11479126
    Abstract: A system for compensating acceleration of electrical motorbike includes a throttle unit and an electro-mechanic assembly. After the electrical motorbike starts, the throttle unit receives external operation from a rider for generating a series of original throttle signal. An acceleration compensating module calculates a throttle variation rate based on the original throttle signal and variation of a throttle operation magnitude, and calculates a throttle compensating value based on the throttle variation rate when the throttle variation rate is larger than or equal to a correction threshold. A throttle compensating module receives and sums the original throttle signal and the throttle compensating value up for generating a new throttle signal. A torque controller generates a corresponding torque command based on the new throttle signal, and outputs the torque command to the electro-mechanic assembly for operation.
