  • Publication number: 20220366099
    Abstract: The invention provides a motor nonlinear system modeling method including steps of: obtaining a chirp signal of a first frequency band, and a chirp signal of a second frequency band; exciting the motor by using the chirp signal; obtaining a higher harmonic frequency response of the first frequency band; exciting the motor by using the chirp signal of the second frequency band; obtaining a higher harmonic frequency response of the second frequency band; obtaining a higher harmonic frequency response by splicing the higher harmonic frequency response of the first frequency band and the higher harmonic frequency response of the second frequency band in the frequency domain.

  • Patent number: 11211888
    Abstract: A motor parameter tracking method, which can dynamically track motor parameters includes: exciting, with a voltage excitation signal, a motor to operate, and acquiring at least one actual voltage across two terminals of the motor and an actual current flowing through the motor in an operating state; modelling a voltage error of the motor based on the at least one actual voltage and the actual current to obtain a voltage error function of the motor; and performing iteration on at least one motor parameter based on the voltage error function and a preset iterative step. With the method, the difference between different batches of motors can be adaptively adjusted, and parameter changes caused by a motor temperature, a motor posture and the like can be dynamically tracked. All motor parameters are provided with a same step, which reduces the difficulty of parameter adjustment and the sensitivity of algorithms to parameters.

  • Patent number: 11151608
    Abstract: Techniques are provided for determining that an item should be provided for presentation to a user based on an item concept relatedness score. For example, a computer system may partition a plurality of items into a plurality of item concepts, whereby each item is assigned to one and only one item concept. The computer system may receive a list of co-selected items, whereby each item of the list is assigned to an item concept. Based at least in part on this list, the system may determine an item concept relatedness score between a first item concept and a second item concept of the plurality of item concepts. The computer system may then receive a selection of a first item assigned to a first item concept. Based at least in part on the item concept relatedness score, the system may provide the second item for presentation to a user.

  • Patent number: 11079853
    Abstract: An actuator excitation signal processing method includes the step of obtaining original excitation signal. An encrypted excitation signal was obtained by encrypting the original excitation signal. Vibration waveforms generated by the encrypted excitation signal and the original excitation signal while acting on the actuator are same. The encrypted excitation signal is used to drive the actuator to vibrate. The actuator excitation signal processing method can effectively solve the problem that the excitation signal might be stolen by encrypting the original excitation signal. In addition, an actuator signal processing device, a computer equipment and a kind of storage medium are also proposed.

  • Publication number: 20210041847
    Abstract: A method for compensating a signal of a motor includes acquiring an original signal and nonlinear parameters of the motor; calculating a compensation signal for the original signal according to the acquired nonlinear parameters; and loading the calculated compensation signal into the motor to excite the motor to vibrate. An electronic apparatus and a storage medium are also provided. In this method, the original excitation signal is compensated for nonlinearity according to the nonlinear motor parameters, and is then used for exciting the motor. Therefore, the actual vibration effect can be closer to the expected effect as designed, which can bring more desirable tactility experience.
