Because the workpiece is in dynamic balance, the resultant moment acting on it should be zero. Introducing the moment from lapping tool and press head a moving differential equation is built. In this equation only workpiece rotating speed is unknown. It means that workpiece rotating speed can be got by this equation. Since there is a transcendental function in integral function of the equation an analytic result can not be got, only digital result can be got by a computer. Thus a change rule of workpiece rotating speed with lapping parameters is known, e.g. the radius of press disc ball socket, radius of press head ball, the distance between the workpiece rotating axis and lapping tool rotating axis, workpiece radius, modulus of elasticity of the press head and press disc, friction coefficients between the lapping tool and workpiece, and between the head and disc, pressure between the lapping tool and workpiece and pressure between the press head and press disc.

The permanent magnet synchronous motor is decoupled into second-order linear speed subsystem and first-order linear flux subsystem. The aim space voltage vector is ascertained by combining sector judgment of stator flux with the practical system inputs after linearization and decoupling. The system is decoupled into two linear subsystems, flux and rotor speed, which realizes the completely dynamic decoupling for permanent magnet synchronous motor speed control system.

So impressive was this invention, so difficult was it to exceed this speed limit, that nearly 3,500 years later, when the first mail coach began operating in England in 1784, it averaged a mere ten mph. The first steam locomotive, introduced in 1825, could have a top speed of only thirteen mph and the great sailing ships of the time labored along at less tan half that speed.

这一发明给人的印象如此之深，要超过它的最高速度又如此之难，以致于过了将近三千五百年，到了公元1784年第一辆邮车在英国运行时，它的时速平均只有十英里。1825年问世的第一辆蒸汽机车，最高时速仅为十三英里，而当时的大帆船仅以不到火车一半的速度在海上慢慢颠簸。

In order to speed up the convergence speed, the each one step of the Landwber iteration is discomposed into the matrix computation and solution and a quick iteration scheme is given for the matrix computation.
