Abstract High voltage piezoelectric stack actuators (HVPSA) are widely used in the field of active vibration control engineering structures due to their strong load capacity, fast response rate, and high mechanical output efficiency. However, inherent hysteresis will have a direct impact on stability efficiency system. To compensate nonlinearity HVPSA, high-precision dynamic hybrid method based linear disturbance rejection (LADRC) is proposed. Starting from analysis actuators, an exponential...
FxLMS (Filtered-x Least Mean Square) algorithm is widely used in the field of AVC (active vibration control) for its good convergence and strong adaptability. However, rate steady-state error are mutually restricted fixed step algorithm. Increasing size <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" id="M1"> <a:mi>μ</a:mi> </a:math> to accelerate will result larger even cause control divergence. In this paper, a new DVSFxLMS (error signal Differential term feedback Variable Step FxLMS)...
The volume control tank (VCT) is an important facility in the primary circuit of nuclear power plants. During normal operation plants, mass transfer between gas and liquid phases occurs VCT at all times. It driven by submerged jets, which may cause potential risks to operational safety necessary conduct in-depth study gain a deeper understanding gas–liquid behavior VCT. In this paper, new model developed that combines surface divergence with CFD accurately simulate process phase into phase....
