Local vector control applied to current control

Current control is the most basic control loop for a current controlled inverter-fed machine. Current controllers fall into two categories depending on the reference frames they operate in - rotating reference frame controllers, and stationary frame controllers. This paper introduces a novel current control technique for inverter controlled machines known as Local Vector Control (LVC). This control technique can be used for the current control loops as well as outer control loops, and can operate without alteration in a stationary or rotating reference frame. Due to its high gain properties it potentially offers excellent transient performance, minimises the effects of disturbances, and operates with varying system parameters. This paper is a preliminary investigation of this algorithm applied to power electronic applications.
