A new all-digital current control technique is presented in this paper. The current control is based on Ramptime current control technique, where multisampling is chosen as the sampling strategy due to its ability to provide higher accuracy. The resultant current control is called Digital Ramptime current control. The performance of the new current control is compared with the original Ramptime in...
One of the most typical representations of the current sense transformer model is the linear model, comprising an ideal transformer, magnetizing inductance and distributed winding capacitance. The magnetizing inductance models the magnetization of the core based on the assumption of a linear relation between the magnetic H and B field. However in reality, the core material exhibits hysteretic and...
Customary of standard control analysis, current control strategies are often tested and compared through applying a step change to the reference current to determine its performance under transients. However, the reality of a step event occurring in this manner for a real system seems unlikely. For a more realistic transient performance indication we should consider the active power filter (APF) application...
Delta robot is a type of parallel robot. It consists of three arms connected to universal joints at the base. In this project, 3 degree of freedom Delta robot use of parallelograms in the arms, this maintains the orientation of the end effectors. The development of the Delta robot corresponds to the current requirement of having a robot able to transfer amount of light object in the least time. In...
