Advanced process control (APC) to the techniques and technologies implemented within industrial process control systems. Advanced process controls usually will arrayed optionally and in addition to basic process controls. Advanced process controls are added consequently, often over the course of many years because to discourse particular performance or economic improvement opportunities in the process. Advance control can also be defined as the implementation of feedforward or cascade control scheme of time-delay compensators of self-tuning or adaptive algorithms or of optimization strategies. Advanced control can regard as more than just the use of multi-processor computers or state-of-the-art software environments and also refer to the singular…show more content…
There is no limit station of the number control parameters. It includes adaptive feedforward control and adaptive time delay. It is truly adaptive regulator. A regulating part which regulates all the control. The regulator is same as an ordinary PID regulator but it contains more control parameters. Moreover the regulating part can also do time delay compensation and feedforward. An adapting part which generates a model of the process when the model changes the control parameters and calculates new values on all. The adapting process can be controlled by inputs on the regulator module; nevertheless it is normally active all the time. Advantages and Disadvantages of Adaptive Controller Adaptive Control Pros Adaptive Control Cons • It adapts easily to the process at start up. • Many regulator parameters can be used. • It’s very simple to design. • The regulator normally operates at much larger production range. • The controller response to change in the process dynamics. • The system relatively slows convergence. • Stability of the adaptive control system is not treated rigorously. • Long period to adapt. • The process is very complex. • High cost is
