Many space-based camera and optical pointing and tracking systems require their line of sight (LOS) to be steady. The Inertial Pseudo-Star Reference Unit (IPSRU) is one of the effective machine which can enhance the sharpness of the camera. In this paper, we design an active disturbance rejection controller to reduce the influence of disturbance. The… (More)
Inertial stabilized platform(ISP) is widely used for line of sight (LOS) stabilization of airborne optoelectronic platform. Due to multiple kinds of disturbances, dynamic characteristics of ISP changes, result in decline of system precision. In this paper, a compound control strategy that combining extended disturbance observer (EDO) and continuous robust… (More)
Here we demonstrate a simple and straightforward approach to prepare POSS-embedded hyperbranched (HB-POSS) polymers with customized molecular weights and sizes just by controlling the polymerization time. The polymers can be further used for building amphiphilic polymers, presenting morphological transition from micelle to vesicle in aqueous solution.
