Title:
制御装置
Document Type and Number:
Japanese Patent JP4350623
Kind Code:
B2
Abstract:
A control system which is capable of avoiding an overloaded state of an actuator without using sensors or the like. An ECU 2 of the control system 1 calculates a lift control input U_Liftin to a variable valve lift mechanism 50 with an algorithm expressed by equations (2) to (5), such that the valve lift Liftin follows up a target valve lift Liftin_cmd, calculates a cumulative value Simot by cumulative calculation of the product of the value Imot of electric current flowing through the variable valve lift mechanism 50 and a sampling time period Stime, and when SImot § Simot_J1 holds, sets two parameters pole_f_1f and ploe_lf to respective predetermined failure-time parameters pole_f_lf_J1 and ploe_lf_J1 which cause the lift control input U_Liftin to become smaller than when Simot < Simot_J1 holds.
