“…A chirp road input disturbance signal of amplitude ±15 mm (Sammier et al, 2003) with frequency increasing from 0-100 Hz (over a simulation period of 100 s), was applied to perform a frequency sweep on the AVSS and PVSS (Savaresi et al, 2010). Spectral analysis was performed on the AVSS and PVSS model outputs with the MATLAB Welch algorithm/spectral estimator.…”

This paper presents the development of a proportional-integral-derivative (PID)-based control method for application to active vehicle suspension systems (AVSS). This method uses an inner PID hydraulic actuator force control loop, in combination with an outer PID suspension travel control loop, to control a nonlinear half-car AVSS. Robustness to model uncertainty in the form of variation in suspension damping is tested, comparing performance of the AVSS with a passive vehicle suspension system (PVSS), with similar model parameters. Spectral analysis of suspension system model output data, obtained by performing a road input disturbance frequency sweep, provides frequency response plots for both nonlinear vehicle suspension systems and time domain vehicle responses to a sinusoidal road input disturbance on a smooth road. The results show the greater robustness of the AVSS over the PVSS to parametric uncertainty in the frequency and time domains.

“…There are two types of active vibration suppression control methods to avoid the abovementioned difficulty. One is the skyhook control method [5][6][7][8][9][10] and the other is the multiple-degree-of-freedom (MDOF) approach [11][12][13][14][15][16][17][18][19].…”

SUMMARYThis paper considers a vibration suppression control method using feedback for a mass-spring-damper system with a tuned mass damper. For vibration suppression, we adopt the interconnection and damping assignment passivity-based control, whereby the system is transformed to a system with a skyhook damper with an artificial structure matrix. The feedback law includes no accelerometer signal and uses only information on relative displacements and velocities. The proposed control method can simultaneously suppress the influences of the floor vibration and the disturbance force acting on the main body. A guideline for choosing parameters of the desired system is shown. The proposed method can be easily extended to nonlinear cases, which is demonstrated for a nonlinear-spring case. We also show the input-to-state stability property of closed-loop systems for linear cases and nonlinear cases.

“…The wheel vertical motion (z us ) and the suspension deflection (z def ) are related to road-holding specifications (Zin, 2005). In the following, four performance objectives are derived from industrial control specifications (Sammier et al, 2003) that are consistent with the one given in (Gillespie, 1992):…”
