It’s little secret that stepper motors are everywhere in FDM 3D printers, but there’s no real reason why you cannot take another type of DC motor like a brushless DC (BLDC) motor and use that instead.

Abstract: For servo mechanisms subject to system uncertainties and external disturbances, one fundamental problem is the effective management of the effects induced by these uncertainties. This ...

We’ve seen a few H-bridge circuits around these parts before, and here’s another application. This time we have an Old Train Station Clock which has been refurbished after being picked up for cheap at ...

Abstract: To address the high-precision control requirements of a three-degree-of-freedom (3-DOF) electro-hydraulic servo robotic arm, this paper innovatively integrates the funnel control (FC) ...
