Abstract
A controller for an inchworm type linear transducer is constructed so as to be extremely low noise and to permit very fine positioning. This is done by storing the desired output waveforms in digital form in an EEPROM memory array and then counting through the address locations of the memory array to re-create the desired waveform. An analog amplifier is used to actually drive the piezoelectric elements in the transducer.
