Design And Development Of Remote Experimental Software In Remote Control Theory Laboratory

With the development of science and technology, the demand of the product quality increases. Therefore, industrial applications need more advanced control methods. However, most of the current control method researches focus on theoretical analysis or simulation verification, which are difficult to directly be applied to industrial applications. The experiment is an important tool in the process of control method applied to industrial applications. So it is of great significance to provide a software and hardware platform which tends to implement complex control algorithm. Remote experiments have advantages of without time-space constraining and experimental resource sharing, which are helpful to the control experiments. Supported by the scientific and technological innovational platform of process industry integrated automation founded by Northeastern university "985project", based on analyzing the development status and trends of domestic and international remote experimental system, this dissertation offers the structure of remote control theory laboratory and the design and development of a new remote experimental software that combines simulation and physical experiments. The model-viewer-controller structure is adapted in this software, which is helpful to software expansion of its structure and functions. Viewer is simple that user is able to use it conveniently; Model embeds application program template that enrich experiments content; Controller packages functional functions that control experimental process, which responds commands quickly. This software is able to achieve variety of complex algorithms study of comparative experiments, and promote complex control algorithms applying in the actual industrial production.This software promotes control algorithms applied to the actual industrial production. The main contributions of the dissertation are summarized as follows:(1)The general framework of the remote experimental software is designed in this dissertation. Based on summarizing and analyzing the function of the remote experimental software, the design concept of view-module-controller architecture pattern is adopted. The software consists of users’interface module, experiment profile module, and communicating interface module, which are helpful to software structure management and function extending.(2)Different types of architecture modules are developed in remote experimental software. Then the server and database need to firstly be configured in software developing environment, achieving to the program application management and experimental data storage. The users’interface in assemble modules includes interface of information and experiment, realizing the function of assessing software system and monitoring experimental process. Experiment profile module involves in simulation and physical experiments, providing references for cases extending. Communicating module includes interface between users’interface and experimental programs, hardware driver interfaces of objects and interface of video image acquisition. The software interface obtains the parameters set by users’interface, and the hardware transfers the control variables, data acquisition and object monitoring.(3)The functions of remote experimental software are verified in the last. M language virtual simulation experiment is conducted on the virtual controlled object of rotary inverted pendulum, which use LQR controller to verify simulation environment. By using information fusion technology, bases on SIMULINK physical control experiments is conducted on physical controlled object, which uses fuzzy logic controller to verify real-time control and the robustness of algorithm. Experimental results demonstrate that most remote control functions are performed by the software.
