Journal ArticleDOI
Optimal Control of Slow-Active Vehicle Suspension — Results of Experimental Data
TL;DR: In this article, an active vehicle suspension of an in-series structure of the slow-active type is presented, where the multidimensional model is reduced to a case representing quarter car suspension.
Journal ArticleDOI
Bench Tests of Slow and Full Active Suspensions in Terms of Energy Consumption
TL;DR: In this article, the authors focused on the problem of active suspensions of wheeled vehicles with electro-hydraulic actuators, and compared frequency response functions and time curves of instantaneous power taken by the active system from supply, obtained at the same excitation signals.
Journal ArticleDOI
Optimal control based on a modified quadratic performance index for systems disturbed by sinusoidal signals
TL;DR: In this article, a modified mean-square performance index with an infinite control time was proposed to evaluate the control laws, based on the decomposition of control signals on the interval from zero to infinity into the sum of sinusoidal components with selected frequencies and an additional auxiliary signal.
Journal ArticleDOI
Application of an SMA Spring for Vibration Screen Control
TL;DR: In this paper, a mathematical model of a controlled SMA spring was formulated and its parameters were identified, both the effect of spring coefficient changes and damping changes depending upon alloy temperature and spring vibration frequency were taken into consideration.
