The invention relates to a proportion integration differentiation (PID) passive control method for near-earth formation satellites. The method comprises the following steps of: S1, establishing a near-earth orbit formation port Hamiltonian system dynamic model; s2, establishing a passive PID (Proportion Integration Differentiation) controller according to the kinetic model, constructing an additional system, and solving a partial differential equation according to the Lyapunov function requirement; s3, designing a Lyapunov function according to a balance point demand, and determining an initial value of an integral item of an additional system; and S4, establishing a PID passive controller based on the initial value of the additional system integral term. According to the method, the problems of difficulty in PID controller parameter selection and poor large-range system performance are effectively avoided, the passive PID control method can be simply and effectively established for the near-earth orbit satellite formation Hamiltonian dynamic system, and the design of the controller is facilitated.

    本发明涉及一种近地编队卫星PID无源控制方法,包括以下步骤:步骤S1、建立近地轨道编队端口哈密顿系统动力学模型;步骤S2、根据动力学模型建立无源PID控制器,构建附加系统,并根据李雅普诺夫函数需求,求解偏微分方程;步骤S3、根据平衡点需求,设计李雅普诺夫函数,并确定附加系统积分项初值;步骤S4、基于附加系统积分项初值建立PID无源控制器。本发明,有效避免了PID控制器参数选择困难、大范围系统表现不佳的问题,可简单有效的针对近地轨道卫星编队哈密顿动力学系统建立起无源PID控制方法,有利于控制器的设计。
