A battery hardware-in-the-loop setup for concurrent design and evaluation of real-time optimal HEV power management controllers
Sharif Razavian, Reza; Lashgarian Azad, Nasser; McPhee, John (Inderscience publishers, 2013-11-03)We have developed a battery hardware-in-the-loop (HIL) setup, which can expedite the design and evaluation of power management controllers for hybrid electric vehicles (HEVs) in a novel cost- and time-effective manner. The ... -
Design and evaluation of a real-time fuel-optimal control system for series hybrid electric vehicles
Sharif Razavian, Reza; Taghavipour, Amir; Lashgarian Azad, Nasser; McPhee, John (Inderscience publishers, 2012)We propose a real-time optimal controller that will reduce fuel consumption in a series hybrid electric vehicle (HEV). This real-time drive cycle-independent controller is designed using a control-oriented model and ... -
Dynamic Modelling and Stability Controller Development for Articulated Steer Vehicles
Lashgarian Azad, Nasser (University of Waterloo, 2007-01-03)In this study, various stability control systems are developed to remove the lateral instability of a conventional articulated steer vehicle (ASV) during the oscillatory yaw motion or “snaking mode”. First, to identify the ... -
An optimal gear-shifting strategy for heavy trucks with trade-off study between trip time and fuel economy
Zhao, Xinxin; Hu, Adam H.; Lashgarian Azad, Nasser; McPhee, John (Inderscience, 2015-11-27)We show how the fuel efficiency of heavy mining trucks can be improved by optimising the gear-shifting strategy. Using characteristic tests of the diesel engine, a high-fidelity model of a mining truck was built in MapleSim ... -
Parametric Importance Analysis and Design Optimization of a Torque Converter Model Using Sensitivity Information
Banerjee, Joydeep; Adibi asl, Hadi; Lashgarian Azad, Nasser; McPhee, John (SAE International, 2012-04-16)Torque converters are used as coupling devices in automobile powertrains involving automatic transmissions. Efficient modeling of torque converters capturing various modes of operation is important for powertrain design ...
