An interpolation strategy for scheduling dynamic compensators

Abstract

This paper presents an alternative interpolation approach for scheduling dynamic compensators. The method interpolates the control signals between design points rather than interpolating the compensator itself. This approach offers more flexibility and simplicity for implementing compensators that are generated from robust multivariable synthesis techniques. It also allows varying order compensators at the design points. The approach is compared to pole-zero interpolation and state-space interpolation. A two-input, one-output autopilot example with two scheduling variables is presented for a tactical weapon.
