Dear Editor, This letter considers the control problem of an experimental flexible manipulator in position tracking, vibration suppression, and saturation compensation. Based on backstepping technology a Nussbaum function, we develop anti-windup to restrain manipulator's vibration, realize desire trajectory eliminate saturation. Applying Lyapunov's method, system's stability with proposed is pr...

A 2-DOF vehicle active suspension system model with time-delay feedback control is established. The stability region of the obtained by using Routh-Hurwitz criterion and polynomial discriminant theory. multi-objective optimization function established taking into account ride comfort, driving safety, handling stability, optimal parameters are particle swarm optimization(PSO) algorithm. vibratio...

The cochlear amplifier is a hypothesized positive feedback process responsible for our exquisite hearing sensitivity. Experimental evidence for or against the positive feedback hypothesis is still lacking. Here we apply linear control theory to determine the open-loop gain and the closed-loop sensitivity of the cochlear amplifier from available measurements of basilar membrane vibration in sens...
