For two-inertia flexible drive system

the traditional pole configuration method can only design the system via representative pole configurations with the same real part

radius

damping coefficient

etc. In order to improve the freedom of system design

the parameter plane method is introduced to solve the problem of parameter design and adjustment. Based on the parameter plane method and PI control strategy

the damping characteristics of the system are analyzed. In response to the under-damping characteristics

the traditional notch filter is introduced

and the suppression effect of the notch filter on mechanical resonance is studied. The results show that the damping stability of the system is closely related to the inertia ratio

and the traditional notch filter can improve the system stability effectively. This study also means the parameter plane method provides an analytical design on two parameter adjustment

and it is very effective and simple.
