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.
