The investigation is aimed at the computer real time system of HAGC for the 2800 plate mill in Wuhan Iron & Steel Company. The hardware structure was based on the multi processor system on a VME bus. Depending upon the complexity of different algorithms and the response time required by the system, a distributed control method was adopted to divide tasks and allocate hardware resources. Based on the real time operating system of VxWorks, mechanisms of multi task, client/server and shared memory was adopted to establish a system structure facing the complicated real time control. Besides, an algorithm block diagram for HAGC control was given. The design has been utilized in actual production, attaining long term results in reliable operation.
