To improve the sensorless control performance of electrical drive systems, a nonsingular terminal sliding mode observer (NTSMO) and adaptive are proposed to solve chattering phase delay problems. Firstly, by defining new surface, based on fast reaching law is designed estimate back electromotive force (EMF). The enhances robustness system eliminates singularity attenuates chattering. Next, obta...

Buildings have long been large energy consumers, and inadequate control of heating, ventilation, air conditioning kinds variable refrigeration flow (HVAC-VRF) lighting systems. To reduce consumption by using a smart building system (SBCS) in was created occupant control, daylight sensors, weather condition variations, load consumed, changes solar power. The model tested MATLAB/Simulink, it then...

Electro-hydraulic systems with regards to the their specific features and applications among other industrial systems including mechanical, electrical and pneumatic systems, have been widely taken into consideration by the scientists and researchers. Due to the fact that the electro-hydraulic system is inherently a nonlinear system, has some problems such as signals saturation, nonlinear effici...
