| Popis: | In this paper, we propose a comparision of GPC and explicit GPC formulations to analyze performance of each algorithm in both offline optimization and online control stage. To demonstrate algorithms performance, we implemented a comparison between three simulated examples: a multivariable control of a Stirred Tank Reactor; an underactuated control of a Gantry Crane System; and multivariable control with transport delay of a Distillation Column. Our results show a reduction in the computational time of control action calculation, from 1.69 to 33 times, depending on the controller. Also, it is possible to significantly reduce memory requirement in explicit cases, depending on the formulation, due to reduced dimensionality. |
