To consider the position control issue, it is necessary to augment the motor equations (1) with Sliding Mode Control 172 Fig. 3. Speed control based on reduced order model and observed state. d w dt θ = (18) where θ denotes the rotor position. ...
The speed and rotational position of the DC motor can be calculated from the measured armature voltage and current estimated with knowledge of the motor constants using electromechanical equations of a DC motor. The motor armature is modelled electrically as a series circuit combination of inductance ...
Motor torque is a combination of the internal torque losses T F (a function of motor design) and external torque load T L . External torque load is a function of load inertia and load acceleration. This will be covered later.What speed range is required?How fast should the motor run ...
This paper reports a novel approach for the modelling of uncertain on initial con- ditions of charge and electrical current for a proportional derivative (PD) control for a direct current (DC) motor. Uncertainties are considered on the exactness of the sensors installed on the driver. The ...

Linear Circuit Definition and Limitations Before we dive into Thevenin’s theorem, let’s discuss the limitations when applying Thevenin’s theorem to linear circuits. In a linear circuit, all the underlying equations must be linear (no exponents or roots). The restriction of Thevenin’s theorem ...
Therefore, d-q transformation is used to transform these nonlinear equations into a linear state model. The electromagnetic torque equations of the PMSM in the rotating reference frame can be written as (2) where ud, uq, id, and iq are the stator voltages and currents, respectively. R is...
