Embodiment Construction

[0100] Hereinafter, a control system according to a first embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 2 , the control system 1 includes an ECU 2 that executes control processing such as variable mechanism control processing in accordance with the operating state of an internal combustion engine (hereinafter referred to as "engine") 3 as will be described later.

[0101]As shown in FIGS. 1 and 3 , the engine 3 is an inline four-cylinder gasoline engine having four sets of cylinders 3 a and pistons 3 b (only one set is shown), and is mounted on an unillustrated vehicle. The engine 3 has: an intake valve 4 and an exhaust valve 7 which are provided for each cylinder 3a to respectively open and close the intake port and the exhaust port; an intake camshaft 5 and an intake cam 6 for driving the intake valve 4; Variable intake valve transmission mechanism 40 for opening and closing driving intake valve 4; exhaust camshaft 8 a...

Abstract

There is provided a plant and internal combustion engine control device capable of improving controllability and control accuracy when controlling a plurality of control amounts while eliminating interference between control inputs and control amounts. A plant (90) has interference between TH_cmd, Liftin_cmd as control input and PB, Gcyl as control amounts. The control device (1) of the plant (90) uses a predetermined control algorithm which combines a predetermined response-specifying type control algorithm (expressions (2) to (8)) and a predetermined non-interference control algorithm expression (9) based on a plant model (expression (20)) in which the plant (90) is modeled as a discrete time system model. The two control inputs TH_cmd and Liftin_cmd are calculated as two non-interference inputs eliminating interference so that PB and Gcyl follow the target values PB_cmd and Gcyl_cmd.

Description

technical field [0001] The present invention relates to a control system of a device with mutual interference between a plurality of control inputs and a plurality of control quantities, and a control system of an internal combustion engine for respectively controlling a plurality of control quantities in an internal combustion engine according to a plurality of control inputs. Background technique [0002] Conventionally, a control system described in Patent Document 1 has been known as a control system for controlling a polishing robot. In this control system, a sliding mode non-disturbance control algorithm combining a sliding mode control algorithm and a non-disturbance control algorithm is used to control the polishing robot as follows. [0003] First of all, the grinding device including the grinding robot is regarded as such equipment: the driving force fmx and fmy of the x-direction and y-direction of the grinding robot are used as two control inputs, and the positio...
