On the optimal feedforward torque control problem of anisotropic synchronous machines: Quadrics, quartics and analytical solutions
Hisham Eldeeb, Christoph M. Hackl, Lorenz Horlbeck +1
The optimal feedforward torque control problem is tackled and solved analytically for synchronous machines while stator resistance and cross-coupling inductance are explicitly cons…

On the equivalence of proportional-integral and proportional-resonant controllers with anti-windup
Christoph M. Hackl
It is shown that proportional-integral (PI) control in the synchronously rotating (d, q)-reference frame and proportional-resonant (PR) control in the stationary (α, \b{eta})-refer…

Non-ideal torque control of wind turbine systems: Impacts on annual energy production
Christoph M. Hackl, Korbinian Schechner
We discuss non-ideal torque control in wind turbine systems (WTS). Most high-level controllers generate a reference torque which is then send to the underlying electrical drive sys…
