This paper presents a novel alignment method based on wander frame for SINS (strap down inertial navigation system) whose initial attitude information is completely unknown. During the coarse mode, the cosine and sine of the wander angle is defined as the filter states, and modeled as the velocity/position error in the geographic frame. Azimuth error state in the fine mode of the filter is defined...
This paper presents a new zero voltage switching (ZVS) bidirectional isolated dc-dc converter, The new topology uses the phase-shift PWM control technology and makes it possible for the switching devices to achieve zero voltage switching, It can reduce voltage and current stress of the switching device, thereby reducing its power consumption, improving efficiency and performance of bidirectional DC-DC...
Standard extended Kalman filtering algorithm usually needs a little precise initial value, but Strap down inertial navigation system(SINS) coarse alignment precision for marching vehicle can't meet the requirement. So UKF (unscented kalman filter) was proposed to achieve SINS initial alignment for marching vehicle with odometer aiding. The state equation for large misalignment error model was expounded,...
