PROBLEM TO BE SOLVED: To provide a steering control device capable of determining the state of an own ship without using a complicated processing such as the analysis of frequency characteristics.;SOLUTION: An azimuth sensor 12 detects a bow azimuth θ_H. An adder 13 differentiates the bow azimuth θ_H from a target azimuth θ_r output from an azimuth setting portion 11 to obtain declination θ=θ_r-θ_H. A control state monitoring portion 14 monitors the time fluctuation of the declination θ. When the fluctuation of the declination is periodical, the declination continuously fluctuates on the basis of the amplitude of the magnitude of a certain degree, and when the angle becomes the center of the fluctuation of the declination approximates 0, the control state monitoring portion 14 determines that the declination is in the oscillation state, and reduces the control parameter of a control portion 15.;COPYRIGHT: (C)2012,JPO&INPIT
