Abstract
To provide an inexpensive attitude control device and attitude control method of a spacecraft for easily and accurately compensating for disturbance with a simple constitution, in a state control device 20 of a moving body constituted by a navigation dynamics 2, an actuator 5 for driving the navigation dynamics 2, first controlling means 4 for controlling the actuator 5 in PID control in response to a first output signal O1 outputted from the navigation dynamics 2 and adding means 10 for outputting a control signal u for controlling the actuator 5 in feedforward control in response to outside noise by adding an estimated value q of the outside noise to a control signal outputted from the first controlling means 4, further installing with second controlling means 9 for outputting an error amount of the estimated value of the outside noise based on a second signal O2 outputted from the navigation dynamics and an error amount value of the estimated value of the outside noise outputted from the second controlling means 9 is inputted to the adding means 10.
