Control problems in solar heating systems are studied. Using a load temperature regulation specification based on minimum temperature, an optimal control problem is formulated to compute a lower bound on the amount of auxiliary energy needed, over a given cycle, for a fixed solar heating system. In order to estimate the sophistication of control necessary for achieving higher performance, a comparative study is made among several simple controllers with both proportional and on-off actuation.

A reduced model has been developed to describe the time evolution of a discharge in an iron core tokamak, taking into account the nonlinear behavior of the ferromagnetic during the discharge. The calculation of the discharge scenario and program regime in the tokamak is formulated as an inverse problem - the optimal control problem. The methods for solving the problem are compared and the analysis of the correctness and stability of the control problem is carried out. A model of “quasi-optimal” control is proposed, which allows one to take into account real power sources. The discharge scenarios are calculated for the T-15 tokamak with an iron core.
