This invention discloses a method and apparatus for planning a timed, fixed-point landing and timed takeoff for lunar sampling missions. The method includes: determining the orbital root number and orbital insertion time of the orbit in the first control phase of the lunar sampling mission, as well as the nominal parameters for timed, fixed-point landing and timed takeoff. Based on the nominal parameters, orbital root number, and orbital insertion time, the first control phase is jointly planned with subsequent control phases to obtain a first deviation, and the first deviation is iterated based on a first variable. When the first deviation is less than a convergence threshold, the target variable for the first control phase is determined, allowing the satellite to achieve timed, fixed-point landing and timed takeoff based on the target variables of each control phase. This achieves dynamic joint planning with timed, fixed-point landing and timed takeoff as the final goal for each control phase, effectively improving the mission's control reconfiguration capability, avoiding additional control operations, and reducing resource consumption.

To solve the problems of traditional virtual synchronous generator (VSG) such as insufficient disturbance rejection ability, noise sensitivity and limited dynamic performance under complex working conditions, a control strategy combining linear active disturbance rejection control (LADRC) and improved adaptive filter algorithm is proposed. By establishing the equivalent model of VSG, virtual inertia and droop control are introduced to reconstruct the operation characteristics of inverter synchronous generator. LADRC is used in the voltage loop to estimate and compensate the internal and external disturbances of the system using the extended state observer, thereby improving the robustness of the system. To solve the noise amplification problem caused by the increase of the observer bandwidth, an LMS adaptive filter is introduced to preprocess the error signal, and a variable step-size LMS algorithm based on the optimized Sigmoid function is used to balance the convergence speed and steady-state accuracy. Finally, a "VSG+LADRC+improved LMS" integrated control architecture is constructed. The simulation and experimental results show that the proposed method significantly improves the disturbance rejection ability and dynamic response under off-grid and on-grid switching and load disturbance, and has good engineering application value.
