New control algorithm for improving thermal efficiency with knock probability constraint
It is important to prevent knock phenomenon in the case where improving thermal efficiency by adjusting spark advance cyclically. In this study, the control algorithm provides the maximum thermal efficiency under the constraint of knock probability by combining the extremum seeking method for thermal efficiency and maximal likelihood-based control for knock probability.
