Filter is a part to degrade the noise during designing electric circuit, it is seldom considered during controlling system design. But it will greatly influence the stability of system. In this paper, the stability of PD controller without filter is analyzed. The oscillation condition and oscillation frequency are given. Simulation validates the results.(More)
Stability control is one of the core technologies of the photoelectric stabilized products. It is difficult for classical control theory to deal with the conflict between the overshot and rapidity and to get satisfied dynamic performances. This paper set up the system mathematical model firstly, and a variable structure controller with integral sliding mode(More)
Magnetorheological damper becomes an active damping control method. It was focused on the research of double cylinder damper with interior coils. The main working modes were analyzed. There were some engineering shortages, such as sealing, heat radiation, greater volume, power supply in the traditional MR damper products. A kind of magnetorheological damper(More)
