Motion Planning and Experimental Validation for an Autonomous Bicycle

Motion Planning and Experimental Validation for an Autonomous Bicycle

This paper introduces a prototype autonomous two-wheeled vehicle developed for experimental verification of motion planning and control algorithms. Finally, it presents and discusses experiments run on the actual vehicle for a particular maneuver. It emphasizes the differences between the trajectories created by different vehicle models.

A Software Architecture for an Autonomous Racecar

A Software Architecture for an Autonomous Racecar

The authors present a detailed description of the software architecture used in the autonomous Roborace vehicles by the TUM-Team. The architecture combines the autonomous software functions perception, planning, and control, which are modularized for use on different hardware and to drive the car on high-speed racetracks.

Control for a Supercapacitor Hybrid Energy Storage System Used in Electric Vehicles

Control for a Supercapacitor Hybrid Energy Storage System Used in Electric Vehicles

This paper proposes the control strategy of a fully active hybrid energy storage system, which uses two bi-directional DC/DC converters to decouple supercapacitors and the battery pack from the DC bus. A Lyapunov-function-based controller regulates DC bus voltage, and a sliding mode controller, controlling the battery and supercapacitor currents, is designed. Their performance is validated by simulation and experimental data.

Minimum Curvature Trajectory Planning and Control for an Autonomous Race Car

Minimum Curvature Trajectory Planning and Control for an Autonomous Race Car

This paper shows a software stack capable of planning a minimum curvature trajectory for an autonomous race car based on an occupancy grid map. It introduces a controller design that allows following the trajectory at the handling limits. The the quadratic optimization problem is extended  for improved accuracy, the introduction of curvature constraints, and the reduction of linearization errors in corners.

Systematic Design of Multivariable Fuel Injection Controllers for Advanced Diesel Combustion

Systematic Design of Multivariable Fuel Injection Controllers for Advanced Diesel Combustion

With multiple fuel injections per combustion cycle, the advanced diesel combustion process depends on all injection pulses in a coupled way. This work describes the cycle-to-cycle fuel injection control problem. A control-oriented model is introduced and locally validated with experimental data. Finally, a systematic design approach is proposed to synthesize a multivariable fuel injection controller.

Independent Generation of Sequence Elements by Motor Cortex

Independent Generation of Sequence Elements by Motor Cortex

Rapid execution of motor sequences depends on fusing movement elements into cohesive units that are executed holistically. The contribution of the primary motor and dorsal premotor cortex to this ability is determined in this paper. Also, the hypothesis that movement elements fuse makes specific predictions regarding three forms of activity, preparation, initiation, and execution is investigated.

Assessment of State-of-Charge Estimation Method for Lithium-Ion Batteries

Assessment of State-of-Charge Estimation Method for Lithium-Ion Batteries

In this paper, a numerical model of lithium-ion batteries is developed and deployed to a Speedgoat Baseline target machine. The estimation method for the state-of-charge (SOC), based on a nonlinear autoregressive with exogenous input (NARX) and artificial neural networks (ANNs) that are correctly trained with multiple datasets, is designed, and experimentally validated by hardware-in-the-loop simulation.
