New Results of Global Exponential Stabilization for BLDCMs System [PDF]

Mathematical Problems in Engineering, 2015
The global exponential stabilization for brushless direct current motor (BLDCM) system is studied. Four linear and simple feedback controllers are proposed to realize the global stabilization of BLDCM with exponential convergence rate; the control law used in each theorem is less conservative and more concise.
