This MATLAB exercise designs and implements a pitch period detector based on detecting and tracking peaks in the autocorrelation of the LPC error signal during regions of voiced speech. The pitch detection procedure is called the SIFT (Simple Inverse Filtering Tracking) method. The SIFT pitch period detector uses a secondary autocorrelation peak in order to detect and correct pitch period detection errors due to effects such as pitch period doubling and related phenomena.

串联式混合动力电动汽车的能量控制策略，恒温控制策略，当电池SOC在合适范围内依靠电机驱动，发动机关闭与否取决于汽车行驶所需要的能量。低于SOC下限时，依靠发动机驱动，多余能量为蓄电池充电。高于上限时关闭发动机依靠电机驱动。((Series Hybrid Electric Vehicle Control Strategy of energy, constant temperature control strategy, when the battery SOC at the right to rely on the scope of motor drive, the engine shut down or not depends on the car of the energy needed. SOC is lower than under the limit, relying on the engine-driven, extra energy for battery charging. Higher than the upper limit of the closure of the engine relies on motor drive.))
