Multivariable Autopilot Design and Implementation for Tactical Missiles
نویسنده
چکیده
A tactical skid-to-turn missile autopilot is designed and implemented using a two step design process that results in an optimal output feedback with a fixed, low-order dynamic compensator for reduced design and implementation cost. The gain design consists of minimizing a performance index in which measurements and controls are appropriately weighted to achieve the desired speed of response, while minimizing overshoot, fin rates, body rates, and maximizing stability margins. The cross channel multivariable autopilot provides faster response times with better stability than does the single channel classical autopilot. The faster response time results in many performance benefits, including smaller miss distance that results in increased lethality, and reduced homing time requirements. This autopilot was implemented and tested in missile-borne microprocessors.

The fundamental objective of autopilot design for missile systems is to provide stability with satisfactory performance and robustness over the whole range of flight conditions throughout the entire flight envelope that missiles are required to operate in, during all probable engagements. Depending on the control mode (skid-to-turn or bank-to-turn), intercept scenario (such as surface to surfac...

Robust autopilot design for bank-to-turn (BTT) missiles under disturbances and uncertainties is investigated in this paper using the disturbance observer concept. It is well known that the BTT missile dynamics undergo a substantial changes during its flight. In this disturbance observer based control setting, the influences caused by parameter variations are merged into disturbance terms and re...

A new autopilot design for bank-to-turn (BTT) missiles is presented. In the design of autopilot, a ridge Gaussian neural network with local learning capability and fewer tuning parameters than Gaussian neural networks is proposed to model the controlled nonlinear systems. We prove that the proposed ridge Gaussian neural network, which can be a universal approximator, equals the expansions of ro...
