在个人计算机PC上设计一简单实时多任务控制系统软件并调试通过。

1、要求至少包括三个相对独立的任务：

（1）键盘和显示器管理

图形显示实时时钟，PV ，SV，MV和P，I，D，MH，ML， ， 等参数，并可通过键盘在线修改，键盘管理应能容错（手/自动切换和输出选做），修改参数时画面应继续显示刷新。

（2）控制计算：构成标准变增益构成标准变增益PID数字调节器。

包括变增益（增益系数0.25），不完全微分，输出限幅，控制周期>4秒。

（3）过程数据采集（模拟计算）

2、上述三个任务构成一个闭环实时控制与管理系统，要求至少分配在不同优先级中进行调度。

-On a personal computer PC to design a simple real-time multi-task control system software and debugging. 1, the requirements include at least three relatively independent tasks: (1) keyboard and display management graphical display real-time clock, PV, SV, MV and P, I, D, MH, ML,, and other parameters, and can be modified online via the keyboard Keyboard management should be able to fault-tolerant (hand/auto switch and output options do), when you modify the parameter screen display refresh should continue. (2) control calculations: standard variable gain constitute constitute standard digital variable gain PID controller. Including variable gain (gain coefficient 0.25), incomplete differential output limiter, the control period>　4 seconds. (3) process data acquisition (simulation) 2, these three tasks constitute a closed-loop real-time control and management system that requires at least assign different priorities for scheduling.
