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…
Power-Controlled Hamiltonian Systems: Application to Electrical Systems with Constant Power Loads
Pooya Monshizadeh, Juan E. Machado, Romeo Ortega +1
We study a type of port-Hamiltonian system, in which the controller or disturbance is not applied to the flow variables, but to the systems power, a scenario that appears in many p…
Conditions on Shifted Passivity of Port-Hamiltonian Systems
Nima Monshizadeh, Pooya Monshizadeh, Romeo Ortega +1
In this paper, we examine the shifted passivity property of port-Hamiltonian systems. Shifted passivity accounts for the fact that in many applications the desired steady-state val…
Stability and Frequency Regulation of Inverters with Capacitive Inertia
Pooya Monshizadeh, Claudio De Persis, Tjerk Stegink +2
In this paper, we address the problem of stability and frequency regulation of a recently proposed inverter. In this type of inverter, the DC-side capacitor emulates the inertia of…
Output Impedance Diffusion into Lossy Power Lines
Pooya Monshizadeh, Nima Monshizadeh, Claudio De Persis +1
Output impedances are inherent elements of power sources in the electrical grids. In this paper, we give an answer to the following question: What is the effect of output impedance…
Nonlinear Analysis of an Improved Swing Equation
Pooya Monshizadeh, Claudio De Persis, Nima Monshizadeh +1
In this paper, we investigate the properties of an improved swing equation model for synchronous generators. This model is derived by omitting the main simplifying assumption of th…
