Servo controller is key part of antenna control system.In some servo controller,classic PID control algorithm is adopted. In order to improve precision of control system,the integral parameter has been turned too big to use because it will cause integral saturation which depress system performance.On the other hand,ISA bus is used to communicate between servo controller and main computer.ISA is low speed interface protocol,it cannot provide more data for complicated real time position control in servo controller.

According to the plane cross section assumption, configuration of a rod is expressed as a history of the cross section with arc coordinate. A special solution which stands for equilibrium in straight line state is obtained from differential equilibrium equation. Linear perturbation equation is derived and its general solution is obtained in which the integral constants are determined by constrained conditions at two ends of the rod. The condition of existence of non zero solution of the integral constants gives to the Greenhill formula of exact elastic rod model, which shows that the boundary of stable area is a closed curve and of symmetry, and inference of shearable and extensible to stability of the rod is depend on three factors: difference between flexibility of shear and extension of a section of the rod, bending stiffness and the length of the rod.
