Embodiment Construction
[0119] The engine control module (ECM) controls the torque output of the engine. More specifically, the ECM controls the actuators of the engine to generate a requested amount of torque based on the target values, respectively. For example, the ECM controls intake and exhaust camshaft phasing based on target intake and exhaust phaser angles, throttle control based on target throttle opening, exhaust gas recirculation (EGR ) valve, and control the wastegate of the turbocharger based on the target wastegate duty cycle.
[0120] The ECM can individually determine the target value using multiple single-input single-output (SISO) controllers, such as proportional-integral-derivative (PID) controllers. However, when using multiple SISO controllers, target values can be set to maintain system stability at the expense of possible fuel consumption reduction. Additionally, the calibration and design of individual SISO controllers can be costly and time consuming.
