Abstract
Based on Infineon XC167, an electronic control system was designed for internal combustion free piston engine generator (FPEG). The displacement was output in form of 4 channel differential signal by Coaxial magnetic grid, so the signal processing circuit was designed, and the displacement signal can be trapped by single-chip micro-controller; according to the current displacement, the ignition pulse width and ignition position was calculated by the single-chip micro-controller, ignition pulse was output; the operation parameter was monitored and control parameter was adjusted by PC. The test results show that: modular design was introduced in the design of electric control system, and it monitors and controls the FPEG accurately, the control objectives are achieved.
