Physical interpretation on anti-resonance in two systems with mechanical flexibilities is presented. It is shown that the anti-resonance is caused by two modes with opposite coefficients determined by the location of actuator and sensor. Notch-type filters are discussed with their physical meaning to compensate the resonance and anti-resonance. It is validated by simulation that for system with non-colocation in the measuring point and working point, compensating resonance would improve the control quality while compensating anti-resonance would not.
