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 ...

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: 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 ...
