A method for controlling combustion in plasma ignition engine is provided. The method includes receiving a signal indicative of a cylinder pressure, determining a location of predefined MBF and COV of IMEP based on the cylinder pressure, and comparing the determined location of predefined MBF with a target location of predefined MBF and the determined COV of IMEP with a target COV of IMEP. When the determined location of predefined MBF has note reached the target location of predefined MBF and the determined COV of IMEP is not less than the target COV of IMEP, the method includes steps to either vary characteristics, such as number of pulses, input voltage, distance between two subsequent pulses, of a plasma shock wave or advance a plasma spark timing. The plasma shock wave is of an order of nanometer.
