Sensorless Control of the Levitated Ball
Alexey Bobtsov, Anton Pyrkin, Romeo Ortega +1
One of the most widely studied dynamical systems in nonlinear control theory is the levitated ball. Several full-state feedback controllers that ensure asymptotic regulation of the…
On the Existence and Long-Term Stability of Voltage Equilibria in Power Systems with Constant Power Loads
Alexey S. Matveev, Juan E. Machado, Romeo Ortega +2
Voltage instability is a major threat in power system operation. The growing presence of constant power loads significantly aggravates this issue, hence motivating the development…
Permanent Magnet Synchronous Motors are Globally Asymptotically Stabilizable with PI Current Control
Romeo Ortega, Nima Monshizadeh, Pooya Monshizadeh +2
This note shows that the industry standard desired equilibrium for permanent magnet synchronous motors (i.e., maximum torque per Ampere) can be globally asymptotically stabilized w…
