The slow orbit feedback at the electron storage ring at DELTA will be upgraded with new software. Finding a set of dipolefieldstrength variations which minimize the deviation of the orbit from a reference orbit requires solving a convex optimization problem subject to inequality constraints. This work focuses on exploiting properties of a special type of interior point methods, which can solve this problem, for orbit correction at DELTA. After comparing runtimes of an interior point method to a Newtonlike optimization algorithm, the performance of the new sloworbitfeedback software is assessed based on measurement results.
