NON-LINEAR OPTIMUM STATE FEEDBACK CONTROL METHOD/ CONTROLLER

摘要

PROBLEM TO BE SOLVED: To most suitably control a non-linear chemical reaction system such as a denitration or desulfurization control device by minimizing the sum of a time integral value from the control start to the termination of a Lagrange's function being the function of a manipulated variable and a state variable and a terminal cost function being the function of the state variable when control terminates.;SOLUTION: In a Lagrange's function and terminal cost function generator 1015, control specification is set as a condition that the sum of the time integral value of the Lagrange's function from the start time of control to the termination time of control and a terminal cost function value being the function of a state variable vector value at the termination time of control becomes minimum or maximum. A phase function computer 1020 calculates a phase function with a state variable vector and time as arguments for calculating a manipulated variable vector for controlling an objective system as in a control specification expressed by the Lagrange's function and the terminal cost function by setting a source function generator 1010, the Lagrange's function and the function generated from the terminal cost function generator 1015 as inputs.;COPYRIGHT: (C)2000,JPO
