We generated parametric curves in the normalizedparameter field and planned the measure-points on parametric curves according to the chordal tolerance.
同时利用规范化参数域生成等参数线，并按照弦公差方法在等参数线上规划测量点；

As the normalized parameters are adopted, the proposed calculating curves are applicable to the parameter optimization for any kind of operation controller of permanent magnetic actuator.
