ANALYSIS OF ENERGY LOSSES IN THE VALVE OF CONTROL SYSTEM

The following paper aims at modelling and analysis of energy losses in the valve of control system. Green-function's method for solution of the PDE (Partial Differential Equations) and Ricatti RDE (Ricatti's Differential Equations) is proposed. Uncertainty of parameters in model of plant is presented and analysed. Frequency characteristics of models are graphically represented and analyzed.
