Embodiment 1

[0023] An embodiment of the present invention provides an actuator simulator, including: a data interface converter and a simulation server;

[0024] The data interface converter is used to receive the control instruction from the on-board computer, and convert the data format of the control instruction into the data format of the analog control instruction, obtain the analog control instruction, and then send the analog control instruction to the simulation server;

[0025] The simulation server is used to receive the simulation control instruction from the data interface converter, and then perform simulation calculation according to the simulation control instruction and the pre-stored mathematical model of the actuator to be simulated to obtain new control force information and new Control torque information, and output the new control force information and new control torque information.

[0026] The working principles of the data interface converter and the simulation s...

Embodiment 2

[0036] In the existing actual satellite system, data communication between on-board devices is carried out through the CAN (Controller Area Network, Controller Area Network) bus, that is to say, the data format input by the on-board actuator is a data format type that conforms to the CAN protocol , therefore, the data format input by the actuator simulator provided in this embodiment is described by taking the data format conforming to the CAN protocol as an example. However, it should be noted that the present invention is not limited thereto. When other data formats are used between devices on the star, for example: when communicating with a type A data format, in the actuator simulator provided by the present invention, the input data format is also Corresponding changes can be made, and all situations that conform to this idea are within the protection scope of the present invention.

[0037] Specifically, the actuator simulator provided in this embodiment includes: an Eth...

Abstract

The invention provides a performer simulator which comprises a simulation server and a data interface converter, wherein, the data interface converter is used for receiving a control instruction from a spaceborne computer, converting a data format of the control instruction into a data format of an analog control instruction to obtain the analog control instruction, and sending the analog control instruction to the simulation server. Accordingly, the performer simulator provided in the invention can be used as a performer simulator of various performers such as a flywheel simulator, a magnetorquer simulator and a thruster simulator simultaneously or respectively, and has the advantages of strong versatility and good scalability; in addition, a data format inputted by the performer simulator is same with a data format inputted by an actual performer physical device in an actual satellite control system, thus the performer simulator can access a satellite control closed loop simulation system, and simulation credibility is effectively raised.

Description

technical field [0001] The invention belongs to the technical field of satellite simulation testing, and in particular relates to an actuator simulator and a satellite closed-loop simulation system provided with the actuator simulator. Background technique [0002] In the early stage of satellite development, it is generally necessary to simulate the satellite control system to verify the effectiveness and advancement of the satellite control system. [0003] As an important part of the satellite control system, the actuator is a key component that affects the effectiveness and advancement of the satellite control system. Therefore, the actuator usually needs to be simulated effectively. A device that simulates an actuator is called an actuator simulator. [0004] At present, when doing closed-loop simulation of satellite control systems at home and abroad, the actuators in the entire closed-loop loop are generally constructed in the following two ways: (1) Physical simulat...
