Abstract

The mathematical models of mechanical system

thermodynamic system and electromagnetic system of a compressor driven by moving-magnet linear motor were established on the basis of the control method that piston's displacement is changed by changing the triac's time of flow. The dynamic performance of the linear compressor was simulated. The voltage and current curves of the motor coil

and the stroke and top dead center of the piston were presented at different time of flow. The simulation results are in good agreement with experimental data. Considering influence of equivalent damping coefficient's changeability

motor parameter's veracity and algorithm

the deviation of the simulation results from the experimental data is less than 10%.
