Abstract: A controller for a plant that can compensate for non-linear property and reduce oscillation of output of a controlled object even when the controlled object has high non-linear property is provided. The present invention provides a controller for a plant that uses PWM algorithm. The device calculates provisional control input for controlling output of the plant at a target value, and divides the provisional control input into a plurality of components. The controller PWM-modulates at least one of the plurality of components, and sums the PWM-modulated component and other components to produce a control input to the plant. The controller minimizes variations in input while maintaining the ability of PWM modulation to compensate for non-linear property of the plant.

Abstract: A valve timing control system for an internal combustion engine, which is capable of accurately and delicately controlling an amount of intake air, and thereby maintaining excellent combustion state and reduced exhaust emissions. The valve timing control system variably controls the valve-closing timing of an intake valve with respect to valve-opening timing of the same as desired via a variable intake valve actuation assembly. The ECU of the engine determined a basic value of a target auxiliary intake cam phase according to the demanded drive torque of the engine. The ECU calculates a control input to the variable intake valve actuation assembly such that the cylinder intake air amount converges to a target intake air amount and at the same time the auxiliary intake cam phase is constrained to the basic value of the target auxiliary intake cam phase.
