Description
  • Prediktivním regulátorem je řízena laboratorní hydraulicko-pneumatická soustava. Problém z pohledu řízení spočívá v snadném přetečení nebo podtečení horních nádrží - hladina v horních nádržích není měřena. Navržený přístup spočívá v použití stavového prediktivního regulátoru (stavy jsou odhadovány Kalmánovým filtrem) s respektováním omezení ve stavových veličinách. (cs)
  • Multidimensional constrained control case study is presented in the paper. Laboratory TITO hydraulic-pneumatic system is controlled by a predictive controller. Problem from the control point of view is overflow or underflow in higher tanks - higher water levels are not measured. Two different predictive controllers according to used process model (input-output or state-space) are discussed and compared. To prevent the overflowing with the input-output model: slew rate limits in the control signal are used, weightings for the control increments are changed and set-points are modified. The state variables (including higher water levels) are estimated in the controller with state-space model ? all state constraints can be considered in control action calculation.
