Torque control strategy is a common strategy to control robotic manipulators. However, it becomes complex duo to manipulator dynamics. In addition, position control of Permanent Magnet Synchronous Motors (PMSMs) is a complicated control. Therefore, tracking control of robots driven by PMSMs is a challenging problem. This article presents a novel tracking control of electrically driven robots wh...

diabetes mellitus is a common metabolic disease. its association with low level of testosterone is controversial. this study aimed to investigate the association between serum total testosterone, free testosterone index (fti), and sex hormone-binding globulin (shbg) in iranian men with type 2 diabetic.a case-control study was conducted on 38 non-diabetic and 36 diabetic men aged 40-60 years old...

the control of fluidized-bed operations processes is still one of the major areas of research due to the complexity of the process and the inherent nonlinearity and varying dynamics involved in its operation. there are varieties of problems in chemical engineering that can be formulated as nonlinear programming (nlps). the quality of the developed solution significantly affects the performance ...

A nonlinear chattering-free sliding mode control method is designed to stabilize fractional chaotic systems with model uncertainties and external disturbances. The main feature of this controller is rapid convergence to equilibrium point, minimize chattering and resistance against uncertainties. The frequency distributed model is used to prove the stability of the controlled system based on dir...

In this paper, we present a data-driven tuning method for model-free control based on an ultra-local model (MFC-ULM), which is also called intelligent proportional-integral-derivative control. industries, the design must be easy, and it important that law can applied to nonlinear systems. The MFC-ULM has most of these features. However, in practice, trial-and-error parameters necessary. To addr...
