1. A control optimization method for a helicopter carrying a suspended load while in hover flight, the method comprising the steps of:

  • designing a helicopter attitude and position tracking controller, the helicopter attitude and position tracking controller generating outputs for stabilizing the helicopter while accepting tracking commands from a reference source and displacement commands from a feedback source as inputs, the design including feedback gain (k) based on minimizing a load swing history, wherein the load swing history is represented by a Linear Quadratic Regulator method, the Linear Quadratic Regulator method depending on minimizing the quadratic function;
