cze Vícerozměrové řízení tepelné soustavy Článek pojedává o návrhu vícerozměrového řízení tepelné soustavy pomocí dvou dvoupolohových regulátorů, dvou PSD regulátorů, pomocí split range a PSD regulátoru a statického kompenzátoru a PSD regulátoru. Popsané metody byly vzájemně porovnány. Vícerozměrová soustava;split range;statický kompenzátor
eng Multivariable control of TISO thermal system The contribution is aimed on problematic of multivariable control. Multivariable system can be generally controlled by a multivariable controller or distributed control scheme can be applied ? the system is divided to several single-input single-output subsystems with individual simple control loops. Special case of the non-square controlled system with more manipulated variables than controlled variables is treated. Thermal system ?Thermostatic bath? as a system with two inputs and one output is controlled by two on-off controllers, two PID controllers, split range and PID controller and by static compensator and PID controller. Control strategies are compared in the view of control quality and costs, information and knowledge required by the control design and application. Discussed problem is interesting because we can reach the desired controlled output with infinitely combinations of the manipulated inputs. This can be used in the case of split range or static compensator and formulate additional control requirements ? to avoid simultaneous heating and cooling by the split range and to follow desired input combination by the static compensator.
