Abstract : This paper describes recent results of a multi-year research effort to develop wideband, high accuracy tracking and weapon pointing control systems through the practical implementation of modern control theory in a state-of-the-art, microprocessor-based, weapon control system. Linear Quadratic (LQ) control laws were applied to an existing weapon system at the hardware level in order to optimize plant performance in the presence of certain non-linearities and mechanical resonance constraints. This hardware approach has enabled us to apply modern control theory to the development of fast response, large scale weapon systems without the degrading limitations usually associated with the plant hardware. Two different optimal control techniques were developed and demonstrated with existing weapon system equipment. One technique was applied to the weapon pointing rate loops, and the other was used to control the electro-optical target tracking sensor subsystem. A practical design procedure, based upon an extensive library of computer programs, that was developed to analyze, simulate, programs, and implement deterministic type modern control systems with higher order dynamics is also described in this paper.
