Linearization of Coupled Pointing and Tracking Dynamical Equations

Cooperative pointing and tracking is one important characteristic of deep space intersatellite laser communication, so that the dynamic mathematical model is complicated nonlinearity and coupling. The contribution of this paper is to substitute the time-domain error transfer function of state equations and to linearize the state space for the sake of physical realization easily in terms of previous authors' work. The method applied is state feedback and coordinate transformation in nonlinear field, the calculated result is demonstrated that differential equations modeled can be transferred into canonical controllable form and realized physically. © (2014) Trans Tech Publications, Switzerland.
