Reduced Order H∞ Missile Controller Synthesis using Critical Characteristic Capture


A methodology has been developed which provides reduced order models which capture critical dynamic response characteristics of full order systems. Performance criteria such as delay time, rise time, peak time and settling time are example measurements which can be used in an optimal parameter estimation technique. Position, velocity and/or acceleration can be matched at any point in a step response trajectory in the most general case. The algorithm functions to estimate coefficients in a chosen linear reduced order model structure. The algorithm is unique since it provides the means to capture any number of point conditions or general characteristics along a full order dynamic response trajectory. Model reduction techniques such as Wilson's cannot directly capture point conditions since they use an optimization criterion which minimizes the difference in response between the full and reduced order trajectories throughout the entire response history. The broad applicability of the Matlab based algorithm is illustrated through application of this technology to synthesis of reduced order H∞ missile autopilots.
