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.

This is a small review of the mini 3D Airplane Kit from Banggood, very nice and does what it should, needs a bit of time to ...

Abstract: In this work, the robust motion control issues of a dc servo system with parametric uncertainty, disturbances, control effort constraints, and saturation nonlinearity are addressed using the ...

Abstract: Electro-hydraulic servo systems are often subject to parameter uncertainties and external disturbances, which degrade position tracking accuracy and control robustness. To address these ...
