We have developed a Small and low power and high performance control system for a motor-driven assist pump.<br>The control system consists of two microcomputers, a programmable logic device (PLD) for address decoding and electronic commutation, a miniature power-FET module for driving a brushless dc motor, a RS-232 driver/receiver. By employing the PLD and by optimum design of a circuit, we have reduced the number of ICs on acircuit board, and have reduced the size of the control system (board size: 64x64mm). The control system has a 16-bit 1-chip microcomputer including a ROM, a RAM, a PIO, a SIO, an A/D, a Timer, a PWM output, and a universal pulse prooessor. The control system has the following various functions; (a) follow-up control system, (b) bi-directional communication with a host computer outside body, (c) adjustment of pump drive parameters from the host computer, (d) control of charge current to a secondary battery. The controller enables us to change drive condition from the outside of the body and to operate the motor-driven assist pump adaptively, based on motor drive dates obtained by the bi-directional communication and physiological test dates.
