The model can be used in the design stage to estimate the maximum jerk that can be commanded without the appearance of overshoot at the tool tip. Also, it can be used to predict the bandwidth of the whole mechatronic system. The model has been tested in a ball screw-based test bench ...
Ramesh T Ramamoorthy, Sam Sabapathy and Santosh K Athuru ABSTRACT The latest C2000™ Delfino™ family of microcontrollers supports fast current loop (FCL) implementation for high bandwidth control of motor drives over a wide speed range in high end multi axes industrial servo control applications...
Modern AC servo drives, depending on the end application, need high-bandwidth current control and speed control to enable superior performance, such as in CNC machines or in fast and precision control applications. Because of the highly time critical computational burden of these systems and the ...
As being independent of the magnitude of reference input signal, the conventional concept of servo bandwidth stemming from electronics fails to reflect the ability of the multiple degree-of-freedom (DOF) mechatronic system to perform vibration control. Considering the magnitude and frequency of reference...
Many systems require that the primary source of DC power be converted to other voltages. Battery driven circuitry is an obvious candidate. The 6V or 12V cell in a laptop computer must be converted to different potentials needed for memory, disc drives, display and operating logic. In theory, ...
Finally, microphone chips with an overall size of 3 × 4 × 1.3 mm3 have been fabricated and preliminary measurements have demonstrated open- circuit sensitivities between 1.4 and 13 mV/Pa, corresponding to bandwidths between 16 and 4 kHz. select article Pressure-sensitive insulated gate field-...
This paper proposes a full-speed-domain position-sensor-less control strategy for precise control under forward and reverse rotation conditions to address the weak convex polarity of surface-mounted permanent magnet synchronous motor (SPMSM). The strategy comprises several key stages: pre-positioning of...
Permanent magnet synchronous motor (PMSM) systems have gained popularity in various fields due to their advantages such as high speed, high accuracy, low maintenance, and high reliability. This paper presents the speed tracking control of a permanent mag
As a result of these improvements, the usable bandwidth in a 100-Mbps network running EtherCAT is more than 90 percent as compared to less than 5 percent for networks where the master must separately communicate with each slave node. EtherCAT telegram As illustrated in Figure 2, the EtherCAT ...
The control design and implementation is detailed in Yu et al. [16] and was based on a limiting of the bandwidth of the controller to avoid the negative aerodynamic damping. In a subsequent campaign in 2016, this time with a TLP floater [17], [18], a similar control implementation was ...
