CD1270: Numerical Optimization Algorithms for Predictive Control
MERL is looking for a highly motivated individual to work on efficient numerical algorithms and applications of optimization based control methods. The research will involve the study and development of novel optimization techniques for predictive control and estimation and/or the implementation and validation of algorithms for industrial applications. The ideal candidate should have experience in either one or multiple of the following topics: convex and non-convex optimization, Newton-type optimization algorithms, numerical optimization (e.g. active-set or interior point) and optimal control. PhD students in engineering or mathematics with a focus on numerical optimization or numerical optimal control are encouraged to apply. Publication of results in conference proceedings and journals is expected. Capability of implementing the designs and algorithms in Matlab is required; coding parts of the algorithms in C/C++ is a plus. The expected duration of the internship is roughly 3 months and the start date is flexible.
