The seat suspension has a significant influence on riding comfort in many practical applications, such as heavy duty vehicles, military and high-speed crafts. This paper proposes equipped with variable equivalent inertance-variable damping (VEI–VD) device novel semi-active vibration control strategy. VEI–VD can its inertance by controlling two external resistors electric circuit. Especially, th...

In this brief note it is shown that the linear matrix inequalities that result from the application of interconnection and damping assignment passivity–based control to general linear time–invariant systems are feasible if and only if the system is stabilizable. A very simple proof of this fact is given that, in contrast to previous results, does not require the assumption that the system has n...

A study is presented on power oscillation damping control (POD) using wide area measurements applied to a single static var compensator (SVC). An equivalent power system model representing key characteristics of the Nordic power system is used. Feedback signals from remote phasor measurment units (PMUs) in Norway and Finland are used to damp the critical inter-area modes through a large SVC uni...

In Japan, low-frequency oscillations have been observed on trunk transmission systems, and have been the subject for studies in fields of operation, control, and devices by many power system utilities. Power system stabilizers (PSS) are very effective controllers in enhancing the damping of low-frequency oscillations, since the controllers can increase damping torque for inter area modes by int...
