The present invention is related to a control system of the reciprocating object comprising a microprocessor (01), a reciprocating mode control circuit (02), a reciprocating travel control circuit (03), a power supply circuit (04) and a motor driving circuit (05), with the microprocessor (01) provided with matrix type on-off signal input-outputs. The reciprocating mode control circuit (02) consists of matrix column branches and matrix row branches, allowing the limited number of the on-off signal ports of the microprocessor (01) to be connected to a plurality of on-off controlling elements thereby realizing a multiple of control modes and diversifying the control modes. The circuit construction according to the present invention is relatively simple, which is helpful to a tidy wiring and layout of the elements and therefore the circuit is easy for manufacturing, assembling, trouble shooting and maintenance.
