Title: One-phase short-circuit fault-tolerant direct torque control method for five-phase permanent-magnet motor

IPC: H02P29/028
Filed: 2019-02-20
Abstract: Disclosed is a one-phase short-circuit fault-tolerant direct torque control method for a five-phase permanent-magnet motor. When phase A experiences an open-circuit fault, a non-faulty phase open-circuit fault-tolerant current, a fault-tolerant transformation matrix T4/2, and an inverse matrix T2/4 for a fault-tolerant operation of the motor are deduced on the basis of the constraints of the flux vector of a stator remaining unchanged before and after a fault, the sum of the currents of non-faulty phases being zero, and minimal copper consumption; when phase A experiences a short-circuit fault, a remaining non-faulty phase compensation flux linkage is deduced on the basis of the constraints of the flux vector of a stator remaining unchanged before and after a fault, the principle of minimal copper consumption or non-faulty phase compensation currents being equivalent in terms of amplitude, and the sum of remaining non-faulty phase compensation currents being zero; and a stator phase voltage instruction is derived by combining a stator flux linkage with a torque observer, a rated torque and a stator flux linkage amplitude, and a coordinate transformation. The voltage combines a pulse width modulation technique based on zero-sequence voltage injection to implement consistent steady-state performance and dynamic performance before and after a motor short-circuit fault; moreover, the frequency of an inverter switch is constant, and the overhead for a CPU is low.

Filed: 2021-11-26
Abstract: The application relates to field of autonomous vehicles that discloses method and system for training a lane tracking system and lane tracking for an autonomous vehicle. During training phase, lane tracking system receives ground truth and measured values corresponding to lane boundary detection points and determines ground truth and measured clothoid points. Thereafter, co-efficient values of clothoid parameters are determined for measured clothoid points to model lane boundaries and then Kalman filter parameters are determined for co-efficient values to track lane boundaries, using Long Short-Term Memory (LSTM) networks. Further, co-efficient values of clothoid parameters are updated using Kalman filter parameters, using which, measured clothoid point is reconstructed, and used to track lane boundaries. Further, training error is minimised based on the difference between reconstructed measured clothoid points and the corresponding ground truth set in each cycle until the training error is below a predefined threshold. The trained lane tracking system is then deployed for lane tracking in the dynamic environment.
