Abstract
The disclosure discloses a signal equalization method including: step S10: calculating an motor excitation signal according to an expected target acceleration signal; step S20: obtaining the output voltage according to the motor excitation signal, and setting the maximum output voltage of the signal power amplifier as voltage threshold; step S30: judging whether the output voltage is less than the voltage threshold. The technical proposal of the disclosure obtains a motor excitation signal and an output voltage by calculating an expected target acceleration signal, then compares the output voltage with the maximum output voltage of a signal power amplifier, improving the security of output voltage; according to the voltage peak area reduction method, the output voltage and the maximum operating displacement threshold of the motor are calculated to obtain a more safe output voltage.
