Suboptimal Control of Power Systems Using Simplified Models

The implementation of optimal control requires the measurement of all the state variables of the system which may not always be possible in practice. Hence a method is proposed by which a suboptimal control policy of a given linear system can be obtained by making use of its simplified model whose order is always less than that of the original system. The suboptimal control policy thus obtained requires the measurement of less number of states of the system, thus simplifying the control structure.
