Abstract or Summary
  • A simple package of routines that can be easily implemented in small minicomputers used in process control, was developed to simulate dynamic systems and computer control of simple dynamic systems found in the process industries. Two different systems, a gas absorber and a fifth-order transfer function were chosen as processes to be simulated. Several control models, like proportional-integral ,direct digital control (DDC), steady-state and dynamic feedforward control and Dahlin's control algorithm were used to control these systems. The gas absorber and the fifth-order transfer function were simulated with an analog computer. The control actions were either done by the analog computer or the NOVA minicomputer. The results were also obtained by simulating the processes and the control actions by using the executive package. The effect of sampling time in DDC control was shown using very fast sampling and slow sampling times. The performance of Dahlin's algorithm for various values of the parameter λ was also shown. The simulation results were compared with the results obtained from analog computer and NOVA minicomputer. It was observed that the results were the same in all cases which indicates that the executive package developed works effectively for systems similar to the test cases.
