  • Patent number: 11913512
    Abstract: A vibration suppression method for a servo motor and a load multistage drive system is provided. For a number N of fixed vibration frequencies and one vibration frequency varying with a load position existing in a multistage drive mechanism, a number of N+1 vibration suppression filters are adopted, and each filter is configured to eliminate a corresponding vibration frequency. Fixed vibration frequencies and a vibration frequency varying with a load position in a multistage drive system are measured by using an offline method, and the varied vibration frequencies are made into a two-dimensional table related to the load positions. The fixed vibration frequencies are eliminated by using fixed-frequency parameter vibration suppression filters; and the varied vibration frequencies are eliminated by using a variable-frequency parameter vibration suppression filter, and the vibration frequencies are obtained in real time according to the load positions and the two-dimensional table.

  • Patent number: 6756838
    Abstract: A charge pump based voltage regulator with smart power regulation employs an architecture that requires that the charge pump current be a linear combination of the load current and a clamp current with a possible offset current. The smart power regulation is based on automatic load activity (or load current) detection using the clamp current. The clamp current and the filtered charge pump current are compared with one another; and the charge pump current is then adjusted accordingly by stepping the frequency of the clock driving the charge pump, optimizing the power consumption of the entire voltage regulator with varying load activity. The negative voltage regulation is independent of the integrated circuit positive supply voltage. In one embodiment, a derivative of the desired output voltage is compared with a reference voltage to generate a clamp current control signal. In another embodiment, the reference voltage is solely positive.
