'Minimum Effort' Adaptive Control of Effluent Treatment, Kilns and Pulp Brightness, 1993 Process Control, Electrical & Information Conference Proceedings
This paper describes the implementation of a remarkable, minimum effort adaptive control strategy. The unique feature of this scheme is the ease of implementing a model-based control strategy as opposed to other model-based and advanced PID approaches employed by previous adaptive control designs. The use of orthogonal filters permits rapid transfer function identification with a minimum of prior process information while maintaining robust control under a wide range of operating conditions. The mathematical model, the development of the software algorithm and the results of several applications at industrial sites are presented.
This paper will briefly review the limitations of PID and adaptive control strategies that exist today and then explain the novel approach we are using in a wide variety of industries. Finally, the results of our field applications in effluent treatment, kiln and pulp brightness control will be presented.
