Abstract:

A nonlinear controller is designed for a full size submarine using the LQGLTR procedure. Linear models of the submarine are developed at four different speeds and then analyzed using the method of modal analysis. The linear models are then augmented with integral control and a Kalman Filter transfer function is designed using some tools for loop shaping. The Loop Transfer Recovery technique is then applied to recover the Kalman Filter Loop shapes. A polynomial data fit is performed on the resulting compensators to produce a nonlinear controller. Both the linear and the nonlinear controllers are extensively tested using a full nonlinear model of the submarine. Author
