The LINK Landscape Architecture and Ecology Doctoral Degree Program, a partnership between three universities (Lisbon’s Técnica and the universities of Oporto and Coimbra), was launched in 2009 with Lisbon hosting its first year before Coimbra took over in 2010 under the direction of Helena Freitas with Oporto running the 2011-2012 academic year supervised by Teresa Andresen. Sixteen doctorate holding professors form the program’s educational core combining to ensure the highest standards in landscape architecture and urban ecology research. The international scope of the LINK teaching program and its staff reflects our intention to endow the program with a global reach, with English as the common language, while nurturing its roots in Southern Europe. As from 2008, the contribution made by by Professor Carl Steinitz, a researcher and Professor at Harvard University throughout four decades, towards launching and running the program has underpinned the doctoral program’s approach to theoretical and practical teaching in the fields of landscape planning and design.

A strategy for adaptive control and energetic optimization of aerobic fermentors was implemented, with both air flow and agitation speed as manipulated variables. This strategy is separable in its components: control, optimization, estimation. We optimized parameter’s estimation (from the usual KLa correlation) using sinusoidal excitation of air flow and agitation speed. We have implemented parameter’s estimation trough recursive least squares algorithm with forgetting factor. We carried separate essays on control, optimization and estimation algorithms. We carried our essays using an original computational simulation environment, with noise and delay generating facilities for data sampling and filtering.
Our results show the convergence and robustness of the estimation algorithm used, improved with use of both forgetting factor and KLa dead-band facilities. Control algorithm used in our work compares favorably with PID using the integrated area criteria for deviation between oxygen molarity and critical molarity (set point). Optimization algorithm clearly reduces energetic consumption, respecting critical molarity. Integration of control, optimization and adaptive algorithms was implemented, but future work is needed for stability. Methods were defined and implemented for stability improvement. We have implemented data acquisition and computer manipulation of air flow and agitation speed for actual fermentors.
