Model Predictive Control of High Power Converters and by Tobias Geyer

By Tobias Geyer

In this unique ebook on version predictive keep watch over (MPC) for strength electronics, the point of interest is wear high-power functions with multilevel converters working at switching frequencies good lower than 1 kHz, comparable to medium-voltage drives and modular multi-level converters.

Consisting of 2 major elements, the 1st deals an in depth evaluate of three-phase energy electronics, electric machines, carrier-based pulse width modulation, optimized pulse styles, state-of-the paintings converter keep an eye on tools and the main of MPC. the second one half is an in-depth therapy of MPC equipment that totally take advantage of the functionality strength of high-power converters. those keep watch over tools mix the quick regulate responses of deadbeat regulate with the optimum steady-state functionality of optimized pulse styles via resolving the antagonism among the two.

MPC is anticipated to conform into the keep watch over approach to selection for energy digital structures working at low pulse numbers with a number of coupled variables and tight working constraints it. Model Predictive regulate of excessive strength Converters and business Drives will permit to reader to profit the right way to bring up the ability potential of the converter, decrease the present distortions, decrease the filter out dimension, in achieving very quick brief responses and make sure the trustworthy operation inside of secure working sector constraints.

Targeted at strength digital practitioners engaged on control-related elements in addition to keep an eye on engineers, the fabric is intuitively obtainable, and the mathematical formulations are augmented through illustrations, uncomplicated examples and a booklet significant other web site that includes animations. Readers reap the benefits of a concise and finished therapy of MPC for business energy electronics, permitting them to appreciate, enforce and increase the sector of high-performance MPC schemes.

Most linear MPC strategies are formulated in the discrete-time domain, using a constant sampling interval Ts . The manipulated variable is restricted to changing its value only at the discrete sampling instants, that is at the time instants t = kTs , where k ∈ N = {0, 1, 2, . } denotes the time steps. 2), the discrete-time representation can easily be computed. 2a) from t = kTs to t = (k + 1)Ts and observing that u(t) is constant during this time interval and equal to u(k), we obtain the discrete-time state-space equation x(k + 1) = Ax(k) + Bu(k) y(k) = Cx(k).
