Abstract

In a remote supervisory control system, graphic user interface (GUI) was used for system communication via monitors. For minimizing operating cost of a process, the automated system was designed, installed and operated properly by a set of optimal control variables. The Response Surface Method (RSM) can be used to find the optimal value of such variables. However, some improper design of an experiment may lead to the process interfering and some actuators damaging. To avoid this issue, a mathematical model of a rotary dryer plant was developed in terms of interested parameters along a dimensionless longitudinal axis. The model was validated by comparison with an actual process operating condition. The trend of the simulated responses was agreed with the real results and its errors of solid temperature, hot gas temperature and solid moisture were 1.79%, 4.72% and 3.54%, respectively. Therefore the model can be used to describe the plant’s behavior and to calculate some optimal operating points for the remote controller in a further work.
