Multi-objective frequency domain-constrained static output feedback control for delayed active suspension systems with wheelbase preview information

Design of Virtual Reference Feedforward Controller for an Active Suspension System

“…With the matrices Q, N and R in ( 9), the new matrices for the augmented system are defined as (23). With those matrices and the augmented system (22), the LQ objective function ( 9) is also augmented with the previewed disturbances as (24).…”

“…With the previewed road profile, a preview control has been applied to date [7,8]. In fact, most of the papers on feedforward control for an active suspension system have adopted a preview control [7,[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Among them, LQ optimal preview control has been widely adopted for designing a preview controller [10][11][12][13][14][15][16]19,21,23].…”

H optimal preview control, sliding mode control and model predictive control (MPC) were also adopted for preview controller design [13,17,18,20,22,24].…”

Vibration suppression investigation and parametric design of tri-axle straight heavy truck with pitch-resistant hydraulically interconnected suspension

“…where symbol * denotes complex conjugate. Δt i ði ¼ m,rÞ is wheelbase filtering time (Zhao et al, 2021) and V is speed.…”

“…Recently, number of research efforts focused on the design and control to improve passive/active safety (Zhang et al, 2020). For instance, Viet and My (2019) revealed the performance limit of system with on-off damping absorber.…”
