Non-linear simulation is used to assess the performance of a fixed linear helicopter flight-control law in maneuvers which are expected to be outside the linear regime. The design of the control law was based on linear considerations, and is analyzed using individual channel analysis. This technique clarifies the conditions under which classical frequency-domain-based analysis can be applied to multivariable systems, with some assurance that robustness problems associated with loop interaction will not occur. It is shown that individual channel analysis can be used to assess the robustness of multivariable control systems with respect to smooth nonlinearities.
