Abstract :
The article describes how to use the resonance/antiresonance characteristics to design a servo control system. A conventional speed control system with a torsional load is analyzed and redesigned. The system frequency characteristics at the resonant/antiresonant frequencies are derived and used to assign the system dynamic behavior. By analyzing the dominant properties at low and high frequencies, a simple magnitude shaping design is developed, and a relationship between the antiresonance and resonance magnitudes is deduced. It is shown that the developed design provides advantages of good response and easy adjustment. The validity of the proposed method is also examined by experiments on a DC motor drive system
