Alignment accuracy and alignment time are two important indexes of the initial alignment procedure of a strapdown inertial navigation system (SINS). However, large misalignment angles will bring nonlinear problems of SINS error models and prolong the convergence time of the initial alignment procedure. In this paper, an innovative control scheme is proposed for the initial alignment of SINS on stationary base, which is implemented by active disturbance rejection control (ADRC). Compared with… CONTINUE READING
