Abstract: The root locus method is one of the fundamental methods in classical control theory, which, however, has not received considerable attention in modern control theory. The gap of the root ...

Based on Quansar’s two-degree-of-freedom helicopter, which has two DC motor propellers for controlling pitch angle θ and yaw angle ψ. Discrete-time controllers are designed for each of these two ...

Abstract: A root-locus method for the analysis of nonlinear servomechanisms is developed, using the complex convolution theorem of the Laplace transformation. The nonlinear servomechanisms that can be ...
