| description | A control device for in internal combustion engine suppresses turbine overspeed rotation and swinging generation of a turbocharger. In the control device for an internal combustion engine, when a target pre/post compressor pressure ratio calculated by a target pre/post compressor pressure ratio calculation part (126) is more than a turbine-limit-time pre/post compressor pressure ratio calculated by a turbine-limit-time pre/post compressor pressure ratio calculation part (122), an upper limit of the target pre/post compressor pressure ratio is limited by the turbine-limit-time pre/post compressor pressure ratio, and a change rate of the target pre/post compressor pressure ratio is limited by a change rate limit value during a change rate limitation period after upper limit limitation processing starts, thereby preventing the target pre/post compressor pressure ratio from being suddenly fluctuated by a sudden fluctuation in a compressor passage flow rate, and suppressing the occurrence of the over rotation of t |
