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 amplimde-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.
