Development of an Integrated Control Strategy Consisting of an Advanced Torque Vectoring Controller and a Genetic Fuzzy Active Steering Controller
Jalali, Kiumars; Uchida, Thomas; McPhee, John; Lambert, Steve (SAE International, 2013-04-08)The optimum driving dynamics can be achieved only when the tire forces on all four wheels and in all three coordinate directions are monitored and controlled precisely. This advanced level of control is possible only when ... -
Parameter estimation of an electrochemistry-based lithium-ion battery model
Masoudi, Ramin; Uchida, Thomas Kenji; McPhee, John (Elsevier, 2015-09-30)Parameters for an electrochemistry-based Lithium-ion battery model are estimated using the homotopy optimization approach. A high-fidelity model of the battery is presented based on chemical and electrical phenomena. ... -
Parameter identification in dynamic systems using the homotopy optimization approach
Uchida, Thomas Kenji; Vyasarayani, Chandrika Prakash; McPhee, John; Carvalho, Ashwin (Springer, 2011-12)Identifying the parameters in a mathematical model governed by a system of ordinary differential equations is considered in this work. It is assumed that only partial state measurement is available from experiments, and ... -
Real-time Dynamic Simulation of Constrained Multibody Systems using Symbolic Computation
Uchida, Thomas Kenji (University of Waterloo, 2011-04-19)The main objective of this research is the development of a framework for the automatic generation of systems of kinematic and dynamic equations that are suitable for real-time applications. In particular, the efficient ... -
Reduction of a Vehicle Multibody Dynamic Model Using Homotopy Optimization
Hall, Andrew; Uchida, Thomas; Loh, Francis; Schmitke, Chad; McPhee, John (De Gruyter, 2013-03-27)Despite the ever-increasing computational power of modern processors, the reduction of complex multibody dynamic models remains an important topic of investigation, particularly for design optimization, sensitivity analysis, ... -
Single-shooting homotopy method for parameter identification in dynamical systems
Vyasarayani, Chandrika Prakash; Uchida, Thomas; McPhee, John (American Physical Society, 2012-03-02)An algorithm for identifying parameters in dynamical systems is developed in this work using homotopy transformations and the single-shooting method. The equations governing the dynamics of the mathematical model are ...
