Latest Patents

Geng Niu's latest patents include a "Method for online direct estimation and compensation of flux and torque errors in electric drives." This online method detects and compensates for errors in flux estimation during the operation of a motor system. It involves determining a voltage compensation term by comparing expected and actual voltages. Additionally, it calculates a flux compensation term using a low-pass filter and determines a corrected flux component value based on a look-up table. The method ultimately calculates a corrected torque value based on the corrected flux component.

Another notable patent is the "Method for direct voltage saturation calculation and prevention of inverter voltage saturation." This algorithm is part of a control method for electric vehicles, which includes an electric motor, a controller, and an inverter. The controller receives a control signal to operate the electric motor and sends a corresponding switching signal to the inverter. The method calculates the expected amplitude of output signals and modifies the instruction to prevent saturation, all implemented in software without additional hardware.
