<P>PROBLEM TO BE SOLVED: To provide an inverter control device and a control system therefor that can relatively maintain or improve resolution of an operation signal operating an inverter, compared with the conventional one. <P>SOLUTION: A control device 60 (inverter control device) comprises: a PI control unit 62 (feedback control means) performing feedback control based on a deviation between request torque T<SP POS="POST">*</SP>for a rotary machine 40 and detection torque T detected actually and outputting a phase command value P<SP POS="POST">*</SP>; operation signal generation means 66 for generating an operation signal Sp that operates an inverter 20 based on a SIN detection signal Ss and a COS detection signal Sc (sensor signal) output from a resolver 41 (rotation sensor) accompanying rotation of the rotary machine 40; and signal multiplication means 68 for multiplying angle information on the sensor signal by a prescribed number. The operation signal generation means 66 generates the operation signal Sp based on the sensor signal whose angle information is multiplied by the signal multiplication means 68. <P>COPYRIGHT: (C)2012,JPO&INPIT |
