Design, simulation and implementation of a class of True Digital Control (TDC) applied to natural gas burner

This paper considers Proportional-Integral-Plus (PIP) control for the hot air extracted from a natural gas burner. The control system has been applied to 7-stages printing machine existed in Cellopack Company for Packing Industries, 6^th of October City. The approach utilizes an experimental data-based modeling in discrete-time basis which suitable for PIP control system design. Here, the full state variable feedback control can be implemented directly from the measured input and output signals of the controlled process, without resort to the design and implementation of a deterministic state reconstruction or stochastic Kalman filter. All requirements are comfortably met for several operating conditions by using a straightforward to implement, fixed gain, linear PIP algorithm.
