Abstract: A motor control system includes an inverter, and a control calculation unit that feedback-controls the inverter. The control calculation unit includes a voltage control calculation unit that calculates a voltage command value indicating a voltage to be applied to the motor from the inverter on the basis of a current deviation between a current command value and an actual current detection value, a torque ripple compensation calculation unit that adds a compensation value for compensating a torque ripple in the motor to a signal value on at least one of an upstream side and a downstream side in a signal flow that passes through the voltage control calculation unit, and a current limit calculation unit that limits the current command value by adaptive control based on an actual angular velocity value indicating an angular velocity at which the motor rotates.

Abstract: A motor control system includes an inverter, a voltage control calculating a voltage command value indicating a voltage to be applied to a motor from the inverter based on a deviation between the current command value and the actual current detection value, and a torque ripple compensation unit adding a compensation value for compensating a torque ripple in the motor to a signal value on an upstream side in a signal flow that passes through the voltage control unit. The torque ripple compensation unit includes a phase compensator calculating a compensation value component in the voltage control unit based on an actual angular velocity value indicating an angular velocity at which the motor rotates, and an inverse characteristic processor calculating a compensation value component for compensating the torque ripple based on an inverse characteristic of an open loop transfer function in a feedback control.

Abstract: An information processing apparatus includes a first controller and a second controller. The first controller performs processing dependent on hardware having a function. The second controller is connected to the first controller via a general-purpose communication path and performs processing not dependent on the hardware. Each of the first controller and the second controller transmits control information used for controlling the hardware to a counterpart controller of the first controller or the second controller via the communication path while varying a transmission interval in accordance with a type of the control information.

Abstract: An information processing apparatus includes a first controller that performs a process dependent on hardware having a function, a second controller that performs a process independent of the hardware, and a power controller that, if there is a reason to resume supply of power to the second controller when supply of power to the first and second controllers has been restricted or stopped, activates both the first and second controllers or only the second controller depending on the reason.

Abstract: An information processing apparatus includes first and second controllers. The first controller executes processing dependent on an individual piece of hardware having a function and stores information indicating an operating state of an individual piece of hardware. The information is different according to the piece of hardware. The second controller executes processing which is not dependent on any piece of hardware. When the information processing apparatus is powered ON, the first controller sends the information stored in the first controller to the second controller. The second controller controls a corresponding piece of hardware by using the information sent from the first controller.

Abstract: An information processing apparatus includes a first controller and a second controller. The first controller performs processing dependent on hardware having a function. The second controller is connected to the first controller via a communication path and performs processing not dependent on the hardware. The second controller stores an execution command in a storage device. The execution command is for executing processing and has a format not dependent on the hardware. The first controller includes a converter, a memory controller, and an operation controller. The converter acquires the execution command from the storage device and converts the execution command into a command for controlling the hardware and dependent on the hardware. The memory controller writes the converted command into a memory. The operation controller reads the converted command from the memory and controls operation of the hardware.
