交互式实时控制系统仿真软件的设计及其在教学中的应用

Design and applications of interactive real -time control system simulation software

交互式实时控制系统仿真软件是一种使计算机在屏幕上以直观的方式,实时地模拟和显示某一过程控制系统运行的程序.系统中可能的扰动,控制器的选定和控制器参数的选定都可以由使用者用鼠标在屏幕上操作来完成.使用这种仿真软件可以替代在有关的实际控制系统上做实验,从而有效地提高学习和培训效率,节约学习的成本.学习设计这种仿真软件有益于学生深入理解控制系统的分析和设计方法,以及学习使用VB6.0或VC++6.0语言编写程序来实施这些设计.

The real -time interactive simulation software of a process control systemis a computer programwhich can simulate the process control system' s running and show the whole system an d its statuses graphically on the screen.All the system' s possible disturbances,the types o f controller,and the relevant param eters of the con-troller can be chosen or set easily wi th a mouse by the software' s user.The usage of this simulation s oftware is e-quivalent with doing experiments on a real process control system,t...
