This paper investigates an optimal pulse-width-modulated (PWM) control of distributed parameter systems by the extension of Kirk's method. The PWM control is assumed to operate on a boundary of a state domain. Using a variational approach, necessary conditions for optimality are obtained.
A solution which satisfies these conditions can be obtained by the gradient method and a numerical example is shown to illustrate the procedure to obtain the solution.
The merit of this approach lies in its applicability to a comparatively wide range of plant dynamics and types of performance indices.
