    • Multipliers 21a and 21b output values, which are obtained by multiplying a total drive command value Es by first and second gains G1 and G2, respectively, as first and second drive command values E1 and E2. Controllers 23a and 23b control first and second actuators (motors) 5 and 7, respectively, on the basis of the first and second drive command values. The detection values of the drive amounts of the actuators are denoted by Ef1 and Ef2, respectively, and the detection value of the drive amount of a driven body is denoted by Ef. A gain calculator 27 calculates the gains G1 and G2 on the basis of Ef1, Ef and Ef2. An upper limit value of Ef, which denotes the drive amount of the driven body, is denoted by Lmax. When Ef1, Ef2 or Ef approaches zero, the first gain G1 is brought close to (Ef1−Lmax/2)/(Ef−Lmax).
    • 乘法器21a和21b的输出值分别通过将总驱动指令值Es乘以第一和第二增益G1和G2作为第一和第二驱动指令值E1和E2获得。 控制器23a和23b分别基于第一和第二驱动指令值来控制第一和第二致动器(马达)5和7。 致动器的驱动量的检测值分别由Ef1和Ef2表示,驱动体的驱动量的检测值用Ef表示。 增益计算器27基于Ef1,Ef和Ef2来计算增益G1和G2。 表示被驱动体的驱动量的Ef的上限值由Lmax表示。 当Ef1,Ef2或Ef接近零时,第一增益G1接近(Ef1-Lmax / 2)/(Ef-Lmax)。
