Abstract:
1. A control apparatus for controlling an internal combustion engine, comprising: a sensor that detects at least one combustion characteristic value related to combustion of the engine; and a control system that determines a desired combustion characteristic value based on engine-and-vehicle operating conditions, and controls a manipulated variable of a variable valve actuation system in a manner so as to bring the detected combustion characteristic value closer to the desired combustion characteristic value; and a dynamic compensator provided to estimate the manipulated variable of the variable valve actuation system based on the detected combustion characteristic value, wherein the control system controls the manipulated variable of the variable valve actuation system, using the estimated manipulated variable obtained by the dynamic compensator, in a manner so as to bring the detected combustion characteristic value closer to the desired combustion characteristic value.
