| Abstract: | In this paper, computer control dynamic study of heat recovery system of Fluidized Catalytic Cracking installation (FCC) , as an example, is discussed. Mathematical models of FCC heat recovery system are established by linearization, otherwise, models, including computer control law calculating lag, A/D and D/A convertion errors, are also deduced. State matrix transition method is used. A sample period is divided into a few calculating steps, and simulating models of actual digital system are also deduced. By simulating the dynamic characteristic, we can design the main data of computer control system. In addition, the general principles to design computer control system of thermal turbo machinery system are obtained. |
