This work presents an integral sliding mode controller, applied to the three-phase induction motor IM using indirect field oriented control technique. Besides seeking high dynamic performance using the slinding mode controller, it is discussed the necessity of a parametric action control (known as equivalent control) to turn the system stable. To do so, it is used an integral sliding mode controller...
Brushless DC (BLDC) motor is used in a wide range of applications due to its high efficiency and high power density. However, as its main drawback, it develops significant torque ripple during phase commutation in conventional 120° conducting mode operation. To reduce torque undulations, this paper presents a simple approach for BLDC motor drive by applying a model-based predictive direct power control...
This work presents a sliding mode controller, applied to the three-phase induction motor using indirect field-oriented control technique. A possible approach for chattering reduction with high degree of robustness is based on the switching saturation function, although it presents steady-state error. This paper, therefore, proposes an integral sliding mode controller with a new anti-windup, which...
Although sliding mode control has many drawbacks when applied to electrical drives due to real limitations of switches, as limited frequency of operation, turn on and turn off delays, some of its theory can be succesfully used in order to project a high performance controller, robust and with a reduced design effort. This paper shows the use of sigmoidal function, hyperbolic tangent, instead of the...
