Abstract:

Systematic procedures for predicting pilot-vehicle-flight control system performance and proneness to pilot induced oscillations and instabilities are here developed and applied to examples. The systems analyzed have very limited maximum control surface rates and deflections. Performance analysis is by means of applying random input describing function theory to predict the root-mean-square level of key system variables as a function of the control surface rate and deflection limit levels. Acceptable limit levels are only two to three times the root mean square value of the variable at the point in the system where each limiter nonlinearity occurs. Results of analyzing three minimum back-up manual flight control system modifications for the F-4C are compared with data from piloted fixed-base simulator experiments for the same system configurations.
