In general, Gantry-type precision stages have low resonance modes because the structure of the stages are large and complex. These resonance modes cause a pitch motion during the translation driving. In this paper, an optimal mechanical parameter design method is analyzed and explored via a two-inertia model. In these modes, primary resonance can be suppressed by Self Resonance Cancellation (SRC)...
The purpose of this paper is development of high-precision trajectory tracking control for nonminimum-phase continuous-time systems with unstable zeros. This paper proposes a two degree of freedom control system design method that is based on a novel factorization method for nonminimum-phase continuous-time systems. First, nonminimum-phase continuous-time systems is factorized to minimum-phase system...
PM motor drive systems are widely used for industrial drives. However, PM motors basically produce the torque ripple due to the fluctuation of the magnetic field distribution. Dead time of the inverter, offset of sensors and current measurement errors lead to the torque ripple, too. The torque ripple leads vibration noises. In this paper, we proposed a torque ripple suppression method based on perfect...
