The performance of a global and a local controller is studied in this chapter. It is well-known that the global controller yields optimal control input in a single step for a linear system. For a nonlinear system, however, the global controller gives only a suboptimal solution, since the transfer matrices (\(\mathbf{T_{i}}\)) are determined only once. Section 5.1 provides a comparison of the performance of global controller with a local controller. Section 5.2 presents the control law sensitivity studies. Section 5.3 explains the noise in hub loads measurements. Section 5.4 gives the summary of this chapter.
