    • A control apparatus that controls a driving apparatus configured with a stator. A variable magnetic flux type rotating electrical machine has a first and second rotor, circumferential direction relative positions of which can be adjusted. A relative position adjustment mechanism adjusts the relative positions of the two rotors. A control command determination unit that determines, on the basis of a required torque and a rotation speed, an inter-rotor phase command indicating the relative positions for minimizing a system loss including at least an electrical loss, which includes a copper loss and an iron loss of the rotating electrical machine, and a mechanical loss of the relative position adjustment mechanism. A current command drives the rotating electrical machine. A control unit controls the rotating electrical machine on the basis of the current command and controls the relative position adjustment mechanism on the basis of the inter-rotor phase command.

    • There is disclosed a sample-and-hold circuit. An operational amplifier includes an inverting input terminal, a non-inverting input terminal, an inverting output terminal, and a non-inverting output terminal. First and second groups of capacitors are operated in first to third modes periodically. Positive and negative input signals are input to charge an electric charge in the first mode, electric charge are held while positive and negative output signals are output from the operational amplifier by connecting between the inverting input terminal and the non-inverting output terminal and by connecting between the non-inverting input terminal and the inverting output terminal in the second mode, and electric charge are discharged in the third mode. Second group of capacitors shifts to the third mode when first group of capacitors is in the first or second mode, and shift to the first or second mode when first group of capacitors is in the third mode.
