【Abstract】 According to the motion characteristics of stepper motor,linear-exponential acceleration and deceleration method of combination of linear and exponent are taken. And the acceleration and deceleration method applies to a specific line and arc acceleration and deceleration process,the minimum deviation method of straight lines and arcs deceleration control algorithms is acquired.Using direct calculation method can easily change in acceleration and deceleration time,maximum start frequency,maximum operating frequency in order to adapt to different processing conditions.But the direct calculation is slower than look-up table.A variety of ways to improve the speed of the direct calculation is put forward,so that the overall acceleration and deceleration approach is more practical.更多还原
