Words Flashcards
Orthogonal
of or involving right angles; at right angles
“The stator current can be broken into orthogonal components in parallel with, and perpendicular to the axis of the rotor magnet.
Aggravate
make (a problem, injury, or offense) worse or more serious.
“… it only serves to produce waste heat and aggravate bearing wear”
Irrespective
not taking (something) into account; regardless of. "... as to always be in the quadrature direction, irrespective of rotor angle and speed"
Misaligned
having an incorrect position or alignment.
“ Because the current space vector can only point in six discrete directions, it is misaligned from the optimal direction by anywhere from 0 to 30 degrees.”
Ripple
a small wave or series of waves on the surface of water, especially as caused by an object dropping into it or a slight breeze.
“ Sinusoidal commutation eliminates the torque ripple and commutation spikes associated with trapezoidal commutation”
Perturbation
a deviation of a system, moving object, or process from its regular or normal state of path, caused by an outside influence.
“Because the PI controllers have limited gain and frequency response, the time-variant perturbations to the current control loop cause phase lag and gain error in the motor currents.”
Empirical
Based on, concerned with, or verifiable by observation or experience rather than theory or pure logic.
“MPCs most often rely on linear empirical model obtained by system identification”
