Abstract

The invention discloses a high-precision precise positioning motion planning method, which comprises the following steps of: parameterizing a motion planning curve, and constructing a speed equation under the condition that the upper limit of speed is Vm and the upper limit of acceleration is am, K is a coefficient related to Vm, and tau is a coefficient related to am; and when the planned distance is x and the speed at the ta moment is x, solving according to the equation set, and if the speed is smaller than Vm, obtaining a high-precision precise positioning motion planning curve according to the equation. The high-precision precise positioning motion planning method provided by the invention can effectively improve the problem of time delay, has the characteristic of asymmetric acceleration and deceleration, and is simple in operation equation and small in calculation amount.

Description

technical field [0001] The invention relates to the technical field of high-precision motion control, in particular to a high-precision precision positioning motion planning method. Background technique [0002] High-speed and high-precision motion control is a research hotspot in modern mechanical engineering technology, which has an important impact on improving the work efficiency and processing quality of mechanical equipment. High-speed and high-precision motion control technology is widely used in many fields such as CNC machine tools and industrial robots. Trapezoidal speed curve and S-shaped speed curve planning are widely used in the field of motion control. [0003] However, the calculation amount of the S-shaped speed curve is large, and the trapezoidal speed curve is prone to overshoot at the turning point when the speed upper limit is reached due to the discontinuous speed change. At the same time, in the point-position control, the two curves have a large lag...
