Abstract?In the solution of a system of equations of the form X=-AX by analog computers, errors will result due to the nonideal characteristics of the integrators and summing amplifiers. In this note a method is given which predistorts the coefficient potentiometers in a manner governed by the models of the active elements which forces the output to be the same as the expected analytical solution. The method does not require the analytical answer to be known before hand.
Index terms?Analog computer solutions using nonideal active elements, correction procedure for analog computer solutions, error considerations in the solution of linear systems on the analog computer, predistortion in analog computer solutions, state model solution on an analog computer.
