Derivation of Stabilizing Controller Based on Minimal-Order Observer and Application to Design of Frequency-Shaping ILQ Servo System

In our preceding paper, a design method for an ILQ robust servo system with a full-order obsever and a free parameter was proposed. In this paper, we propose a similar method for an ILQ servo system with a minimal-order observer and a free parameter. First, we derive a stabilizing controller based o...

Zusammenfassung:In our preceding paper, a design method for an ILQ robust servo system with a full-order obsever and a free parameter was proposed. In this paper, we propose a similar method for an ILQ servo system with a minimal-order observer and a free parameter. First, we derive a stabilizing controller based on a minimal-order observer from a full-order observer-based stabilizing controller by equivalent transformation. Then we apply it to design a frequency-shaping ILQ servo system. Finally, we show a design example for a magnetic levitaion system.
