- Abstract
- The use of adaptive control algorithms was studied for microprocessor driven direct digital control of elementary heating and cooling subsystems. An algorithm was designed for digital regulation of a linear, time-invariant first-order system with a system dead time. A recursive least squares algorithm was used to estimate, on-line, the parameters of the time-invariant linear system. The parameter estimates were then used to calculate the feedback gains of a Proportional plus Integral (PI) controller.
