    • CA1904: Numerical Optimal Control for Hybrid Dynamical Systems

      MERL is looking for a highly motivated individual to work on tailored computational algorithms for numerical optimal control of hybrid dynamical systems and applications for decision making, motion planning and control of autonomous systems. The research will involve the study and development of numerical optimal control methods for systems with continuous dynamics and discrete logic, nonsmooth and/or switched dynamics, and the implementation and validation of such algorithms for industrial applications, e.g., related to autonomous driving and robotics. The ideal candidate should have experience in either one or multiple of the following topics: mixed-integer programming (MIP), mathematical programs with complementarity constraints (MPCCs), modeling and formulation of optimal control problems for hybrid dynamical systems, convex and non-convex optimization, machine learning and real-time optimization. PhD students in engineering or mathematics, especially with a focus on MIPs, MPCCs or numerical optimal control, are encouraged to apply. Publication of relevant results in conference proceedings or journals is expected. Capability of implementing the designs and algorithms in MATLAB/Python is expected; coding parts of the algorithms in C/C++ is a plus. The expected duration of the internship is 3-6 months and the start date is flexible.

    • CA1939: Motion Planning, Estimation and Control for Articulated Vehicles

      MERL is seeking a highly motivated and qualified intern to collaborate with multiple researchers on the improvement, real-time implementation and experimental validation of algorithms for path/motion planning, constrained state estimation, optimal control and reference tracking in autonomous articulated vehicles. The ideal candidate should have a background in either path/motion planning, state and parameter estimation and/or model predictive control (MPC) for autonomous (articulated) vehicles, and the candidate should have experience in one or multiple of the following topics: optimal control, MPC, vehicle dynamics, A* search, RRT, Kalman filtering, particle filtering, and machine learning. Capability of implementing the designs and algorithms in Matlab and Simulink, and using C/C++ code generation is expected. Any experience with dSPACE (e.g., MicroAutoBox or Scalexio), CasADi, and/or experience with vehicle experiments or simulators (e.g., TruckSim or CarSim) is a plus. Publication of relevant results in conference proceedings or journals is expected. MS or PhD students in control, robotics, electrical and mechanical, or related areas, are encouraged to apply. The expected duration of the internship is 3-6 months and the start date is flexible.
