YUE Ming, DENG Zong-quan. Design of state feedback control system for spherical robot based on state observer[J]. Optics and precision engineering, 2007, 15(6): 878-883.DOI:
The dynamic equation of a spherical robot was established
and a nonlinear affine system is derived based on energy dissipation Lagrangian equation. Linearization and affine transformation methods are used in the new equilibrium point to design control system by a powerful linear theory
according to the actual movements and theoretical simulated datum of robot. A state observer is built for estimating full state variables of system in real-time because some of state variables are immeasurability. The state feedback controller is designed and the simulation results prove the validity of the controller.
