The equipment requested in this proposal will be used to build a real time hardware-in-the-loop (HIL) simulation platform for advanced control system design. In particular, it is expected to be used to support research activities about control systems for HCCI combustion engines and fault tolerant control of electric power steering systems, both at fundamental and application levels. Specifically, the following research projects currently conducted by the applicant will extremely benefit from the proposed platform: 1. Intelligent ignition timing control for HCCI combustion engines: Among the choices of operating mechanism for next generation of automotive engines, HCCI is on top of all others due to its potential to provide high fuel efficiency yet low emission operation and its flexibility to accommodate different fuel such as gasoline, diesel, alternative fuel, natural gas, etc. Novel intelligent control mechanism is required to facilitate the HCCI operation. For this account, intelligent control strategy for optimal HCCI operation with fuel mixture is investigated.      2. Fault tolerant control for electric power steering systems: Electric power steering (EPS) systems have been accepted at an accelerated pace by the automotive industry as an effective solution to replace hydraulic power steering systems, due to various advantages of EPS systems including fuel efficiency, safety, and low cost for both manufacturing and maintenance. Among the key issues to be resolved in an EPS system, fault tolerant control is the most important one to guarantee safety and reliability during operating processes. Currently, the applicant is conducting research on exploring model based fault detection and tolerant control for the EPS system using brushless motors.
