HCCI Diesel Engine Control Design using Advanced Simulation with Real Time Capabilities

Active Combustion Control of Diesel HCCI Engine: Combustion Timing

We propose a model based control strategy to adapt the injection settings according to the air path dynamics on a Diesel HCCI engine. This approach complements existing airpath and fuelpath controllers, and aims at accurately controlling the start of combustion. For that purpose, start of injection is adjusted based on a Knock Integral Model and intake manifold conditions. Experimental results ...

Airpath strategy for experimental control of a Diesel HCCI Engine

A motion planning based control strategy is proposed for the airpath control of turbocharged Diesel engines using exhaust gas recirculation (EGR). The considered model uses simple balance equations. The fully actuated dynamics are easily inverted, yielding straightforward open-loop control laws. This approach is complemented by experimentally derived look-up tables to cast the drivers requests ...

Real-Time Combustion Parameters Estimation for HCCI-Diesel Engine Based on Knock Sensor Measurement

Future internal combustion engine technologies require an accurate combustion monitoring and control. This can be performed through high frequency recordings of cylinder pressure. However, this solution is limited by the sensor cost and reliability. Another method consist in reconstructing combustion related variables from indirect measurements. In this paper, we propose a combustion indicator ...

Control Design for a Diesel Engine Model with Time Delay

The concept of control Lyapunov function has proven a useful tool for designing robust control laws for nonlinear systems. Recently, this concept has been extended to time-delay systems in the form of Control Lyapunov Razumikhin functions and Control Lyapunov Krasovsky functionals (CLKF). Universal formulas, such as Sontag's formula and domination redesign formula, apply to CLKF's and achieve r...
