Embodiment Construction

[0026] A slide mode control device according to a first preferred embodiment of the present invention will now be described. The slip mode control is used in the control of solenoid engine valves.

[0027] Since the intake valve and the exhaust valve basically have the same structure and are controlled in the same manner, the exhaust valve will be mainly described in this embodiment.

[0028] The exhaust valve, which is a controlled object, has a first elastic part and a second elastic part. The first elastic member pushes the valve body to move toward the first end. The second elastic member pushes the valve body to move toward the second end. An armature is connected to the valve body. An electromagnetic force is applied to the armature such that the valve body is selectively attracted to the first moving end and the second moving end.

[0029] In particular, if figure 1 As shown, the exhaust valve 1 includes a valve shaft 4, a valve body 2 located at one end of the va...

Abstract

A valve of an internal combustion engine includes a valve body movable between a fully opened position and a fully closed position, an armature coupled to the valve body, a pair of springs urging the valve body, and a pair of electromagnets. Each electromagnet generates electromagnetic force to attract the armature, thereby moving the valve body. The engine valve is controlled by means of sliding mode. That is, when the valve body is moved from the fully closed position to the fully opened position, the electromagnets are controlled such that the state quantity of the valve body (the position and the moving speed) converges on a previously set switching hyperplane. The switching hyperplane is changed in accordance with the position of the valve body. As a result, a number of factors required for controlling the engine valve are satisfied.

Description

technical field [0001] The present invention relates to a sliding mode control device and a sliding mode control method for controlling an elastic system such as a spring-mass system. Background technique [0002] For example, Japanese Laid-Open Patent Publication No. 9-217859 discloses a control system having a spring-mass system such as a solenoid valve. In this control system, state quantities including, for example, the movement amount and movement speed of a controlled object are feedback-controlled by such as proportional, integral, derivative (PID) control, so that the above state quantities can follow a target state quantity. However, the robustness of existing control methods such as PID control cannot reliably maintain the ability to resist disturbances and changes in the characteristics of the controlled object. [0003] Accordingly, sliding mode control has been applied in such control systems. In sliding mode control, the state quantities of a controlled objec...
