A dynamic performance compensator design for servo system based on notch filter

With the development of times. Flight Simulator getting higher and higher frequency-domain performance requirements, in order to suppress the system´s mechanical resonance and improve the system dynamic performance in wider broadband domain. Design this complex inverted notch filter, using the method that through the notch filter´s amplitude-frequency characteristics compared to actual system´s amplitude-frequency to suppress the system´s mechanical resonance and improve the system dynamic performance in wider broadband domain. And through experiment prove the effectiveness of the method.
