Direct Digital Control

The implementation and performance of direct digital control algorithms in a microcomputer-based controller was studied in relation to the control of nonlinear thermal processes. Particular emphasis was given to discrete algorithms such as proportional-integral and finite time settling control algorithms. Experimental studies were carried out with a nonlinear diffusion furnace controlled by an Intel 8080-based microcomputer system, on which the control algorithms were implemented. The performance of different, modified, linear control algorithms were evaluated in thermal process control applications.
