This paper presents a control of active suspension for quarter car model with two degree of freedom by using H∞ method. Absolute velocity of car body is measured for feedback. The system parameter variations are treated with multiplicative uncertainty model. Simulation results show that the H∞controller provides good trade-off between ride quality, suspension packaging and road holding constrai...

Antistreptolysin O (ASO) titers were determined on 117 human sera with rabbit, human, and sheep red blood cells (RBC) as the indicator system in the ASO tube test. The titers of 65% of the sera were one dilution step higher when a 5% suspension of sheep RBC was used instead of a 5% suspension of rabbit RBC. Titers were one dilution step higher in 42.7% of the sera when a 5% suspension of human ...

The objective of this paper is to provide directional control during handling maneuvers and effective isolation of passengers or pay load from road disturbances. Active suspension system is considered to be a way of increasing the freedom that one has to specify independently the characteristics of load carrying, handling and ride quality. In this paper, a quarter bus suspension system is simul...

Between 2010 and 2014, the research team of Josef Bozek ́s Research Center of Combustion Engines and Automobiles at the Czech Technical University in Prague, Czech Republic, has developed innovations in vehicle suspension technology. The research team has designed a unique innovative suspension system that uses a linear electric motor as a controlled actuator. We have undertaken many experiments...
