Abstract By controlling the angular speed of the servomotor to realize all the parameters of non-sinusoidal oscillation adjusted online, an oscillator synchronously driven by two symmetry laid servomotors turning in the opposite direction was proposed. Firstly，the working principle of the oscillator was explained. And the three-dimensional model of the system was established. Secondly, the global function of non-sinusoidal oscillation waveform was analyzed. Meanwhile, the angular speed of servomotor to realize non-sinusoidal oscillation waveform of global function was presented. The calculation methods of technological parameters were given and the multi technological parameter curve was obtained. Based on the technological parameters of a caster for a plant, the synchronous control model of among the casting speed, oscillation frequency and amplitude was determined. The results show that technological parameters of non-sinusoidal oscillation can meet the requirement of value limit in theory, which provide an important reference for shallowing oscillation remark, improving the lubrication condition between mold and slab, enhancing casting speed and slab surface quality further.
