This paper presents an experiment for optimal current-control of permanent magnet synchronous motor, of which robust and simple current controller is designed without subjoining the estimating or lagging compensator, by analytical procedure of the inverse LQ design method. The ILQ design method is a strategy to find the optimal gains that is based on pole assignment without having to solve Riccati equation. By comparing with conventional PI control, it is quantitatively confirmed that the ILQ control is excellent in robust for variations of the motor's parameters. The results obtained give experimental verifications for simulation results which we had already reported.
