MPC for Multi-level Inverters
Betreuer: Prof. Dr.-Ing. Ralph Kennel (Wuppertal)

Model Predictive Control (MPC) is a so called long-range predictive control strategy; therefore the prediction horizons could be longer than one sample step. The most known drawback of MPC in industrial applications is, however, its online implementation complexity, especially in fast sampling-time applications. To overcome this disadvantage Bemporad et al. proposed an algorithm to move the time-consuming part of the control off-line. This algorithm determines explicitly the state feed-back control-laws associated with MPC and shows that there are piecewise affine (PWA) functions. This algorithm uses the state vector as a parameter to solve the optimization problem (Multi- Parametric Programming), and the resulting control actions will be PWA functions. To control the system the controller has just to find out, which PWA function must be applied for the given system state vector, and then evaluates the appropriate linear control-law. This reduces the online computational effort of the optimization problem to a simple look-up-table, which could be used in the electric drive, where fast sampling time is normally required. To build the LUT and extract the control-laws during the implementation there are different algorithms, which reduce the elapsed time to get the proper PWA function from the stored data.
