Limitations in Active Suspension Systems
Original language description
It is often assumed that if practical difficulties are neglected, active systems could in principle produce arbitrary ideal behavior. Using a simple linear two degree-of-freedom car suspension system model it will be shown that even using complete statefeedback and in the case of in which the system is controllable in the control theory sense, there still are limitations to suspension performance in the fully active state. In control law design for active suspension system of vehicles it is demanded toprevent magnitudes of the road and load frequency responses from being too large. The paper aims to show that there are some frequency points and frequency ranges where the transfer functions have modulus strictly greater than one i.e. where road and load disturbance amplification occurs. On the base of the Bode integral theorems a proof will be given to show that the transfer functions must be greater in modulus to at least the same extend that it is less than one, when measured in ter
