This paper presents the application of the asymptotically positive realness constraint (APRC) in the stabilization for interconnected systems with a descriptor system approach. Handling parallel redundant subsystems that have unknown splitting ratios is an essential part of this development. We have introduced the parallel masking technique in previous work(More)
This work presents a nonlinear lead-lag controller synthesis for a nonlinear unstable system. Nonlinear lead-lag controller is design based on describing function technique. Unstable system will first be stabilized by designing a stabilizing controller. System will then be excited by known sinusoidal input to generate describing function model of the(More)
