This paper presents two kinds of learning control methods-P-Integrator learning control and self-tuning control with learning parameters. Their application of piezoelectric cutting tool to ultra-precision manufacturing is also introduced. By means of using advanced control methods,the non-linear and hysteresis characteristics of piezo-element can be overcome and high precision locating and zero-error tracking control can be achieved easily.
