Abstract:
This work investigates the use of the Locus of Perturbed Relay System (LPRS) to analyze oscillations in homogenous sliding mode controllers in the condition of absence of parasitic dynamics. The homogenous sliding mode controllers produce either finite time convergence or non-vanishing oscillations under different combinations of system and controller parameters. The undertaken LPRS analysis reveals that multiple frequency solutions exist for the systems of different relative degrees. Solutions of the nonlinear equations of the LPRS are computed numerically to determine these frequency points. Simulations are done to see the behavior of these solution frequencies, which shows that some of these are stable frequency points while others are unstable.
