This paper introduces the research on the inductance‐capacitor‐capacitor‐inductance grid‐connected inverter using active disturbance rejection and grid voltage feedforward coordinated control technology. The pade approximation is performed on the inductance‐capacitor‐capacitor‐inductance filter to derive the first‐order discretization mathematical ...

Robust synthesis of feedforward compensators
Summary: The design of a feedforward compensator for robust \({\mathcal H}_\infty\) or \({\mathcal H}_2\) performance under structured uncertainty is considered. For linear time-invariant uncertainty, a convex method based on linear matrix inequalities (LMI's) across the frequency variable is given.

Current Harmonic Suppression Algorithm for Asymmetric Dual Three-Phase PMSM
Based on the vector space decomposition (VSD) transformation, the currents of an asymmetric dual three-phase permanent magnet synchronous motor (ADT-PMSM) with isolated neutral points are decoupled into the torque, producing α-ß components in ...

Multislope PI Modeling and Feedforward Compensation for Piezoelectric Beam [PDF]
The hysteresis nonlinearity greatly reduces the tracking precision of piezoceramic actuators for expected displacement in a high-accuracy positioning system. In order to effectively compensate the hysteresis for piezoelectric ceramics, a novel modeling method, namely, multislope PI (Prandtl–Ishlinskii) was proposed.
