With the wide applications of model predictive control, a variety of algorithms for solving online quadratic optimization problems have been proposed. As different algorithms have different characteristics, it is important to assess the performance of these algorithms and to select the appropriate online optimization algorithm for a given model predictive control problem. This paper outlines the appropriate assessment criteria so that the performance of various algorithms can be fairly assessed. Then a guideline to select the suitable algorithms for actual model predictive control problems is provided and described in detail. Furthermore, the calculation results from a number of typical model predictive control problems with different optimization algorithms are listed and compared.
