Self-calibration in Power-train Systems with Time-Delay
Novel adaptive algorithms for Fully Adaptive Self-tuning (FAST) Controls in Powertrain Systems where time-delay plays a major role in performance optimization are being developed. FAST control strategies have the potential for reducing the calibration time and improving the performance in highly uncertain nonlinear dynamic systems. The concomitantly present hallmarks of ever increasing complexity and stringent performance targets in powertrain systems, which become stronger and harder to achieve in the presence of time-delays, warrant the use of such adaptive algorithms. A unique methodology termed Adaptive Posicast Control has been developed in the lab, which has shown enormous improvement in gas turbine systems with large time-delays and have stringent performance specifications of safety and emissions. This Posicast control technology is being applied in Powertrain systems such as idle-speed control where time-delay plays a prominent role, where the expected impact is in the improvement of fuel economy.
