Philip Wallstedt Email & Phone Number | Path planning, vehicle modeling and on-board simulation for fully autonomous mining trucks. Development of performance and stability maps to keep speed within constraints of lateral acceleration, field-of-view, emergency stopping time, and mechanical wear limits. Design of proving grounds tests for assessment of performance and stability. Development of balance-of-power models to predict engine load in a wide variety of scenarios to enable on-board estimation of rolling resistance. Kinematic and Dynamic modeling for Electric Rope Shovel to calculate precise dipper position based on crowd, hoist, and swing in local and global coordinates. 100Hz computation of time-to-stop for any initial condition of the dipper. Models of PID controllers, engine maps, and slew rates to enable several kinds of on-board safety and performance simulations. Development of real-time bucket / blade / dynamic terrain models. Parallelization, integration, and validation of software for simulations of manufacturing, earthmoving, mining, and dozing operations. Development of distributed-memory parallelized implementations of meshfree and finite element methods. Non-linear matrix-free Newton-Krylov solvers. Explicit time integration.
