Problems solved by technology

But this method also has the following obvious deficiencies: First, the user cannot modify the sensor model and actuator model in the aero-engine control system online, because the aero-engine control system described in this method does not provide users with online modification of the sensor model and execution mechanism model. The interface of the mechanism model; second, when the user modifies the control algorithm model, the new control algorithm model will directly replace the original version, so the version control of the control algorithm model cannot be achieved; the third is that there is no multi-user collaborative design and Integrated functions

[0030] Example 3. image 3 It is a schematic diagram of multi-user collaborative design and integration functions proposed by the present invention. image 3 The multi-user collaborative design in the system is an important function of the present invention. This function requires multiple users to access the server at the same time, in different places and independently, and perform analysis, design and verification of the aero-engine control system. influences. In order to realize this function, the server creates a personal workspace for each user, and copies the model side to this space to create a copy of the model for users to modify, compile and use, while the baseline version of the model side remains unchanged. The running status of the model will also be fed back to the user in a timely manner. The schematic diagram of the working situation of the client when the user accesses the system is as follows: Figure 5 As shown, the user selects the engine model to be us...

Abstract

The invention relates to a multi-user co-simulation resource scheduling method for an aero-engine control system. The method is characterized in that an aero-engine control system multi-user co-simulation comprises a server, a client-side, and a model-side. The client-side and the server, and the client-side and the model-side perform data communication through a TCP Socket communication protocol, realizing functions of multi-user co-design and integration in a real sense. The multi-user co-simulation resource scheduling method can satisfy base course requirements of development of an aero-engine control system, can prevent repetitive work in modeling of the aero-engine control system, and users are permitted to modify controller / sensor / executing mechanism models. In addition, the method supports multi-user co-design and integration, so as to greatly improve research and development efficiency and reduce research and development cost.
