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.
