Abstract

The invention discloses a drive control device and method of a macro-micro drive piezoelectric liner motor. The drive control device comprises a controllable rectifying circuit, a positive-negative current output adjustable high-frequency switch circuit, a photocoupling isolation drive circuit, a two-phase alternating-current output inversion circuit and a micro controller circuit, wherein under the cooperative control of the micro controller circuit, after the positive-negative direct-current output adjustable high-frequency switch circuit boosts the output direct-current power of the controllable rectifying circuit, a positive direct-current voltage and a negative direct-current voltage are outputted to be used as a power source of the alternating-current output inversion circuit; after a control signal of the micro controller circuit is isolated and amplified by the photocoupling isolation drive circuit, the two-phase alternating-current output inversion circuit is driven to generate a sine drive signal needed by the macro movement or a direct-current drive signal needed by the micro movement. The drive control of the macro-micro movement integrated piezoelectric liner motor can be realized, not only can the sine drive signal needed by the macro movement be outputted, but also the direct-current drive signal needed by the micro movement can be outputted.
