Pulse uniformity control algorithm

Abstract

The invention discloses a pulse uniformity control algorithm. The pulse uniformity control algorithm comprises four-channel encoders, a frequency division function, a variable spacing function, a fixed frequency function and a self-start-stop function. According to the invention, any two count values in the four encoders are selected through parameters to participate in frequency division calculation and are marked as X / Y, a parameter input frequency division distance delta is marked as L, high level time is marked as outtime, and synchronous signal waiting time is marked as delaytime; and the pulse counting increments deltaX and deltaY of XY are obtained through counting, and when the frequency division function is started and the equation that deltaX * deltaX + deltaY * deltaY = deltaL * deltaL is satisfied, a synchronization signal or the synchronous signal waiting time large delay time is received. The invention relates to the field of automatic control engineering. According to the pulse uniformity control algorithm, a connection speed between equal-period control and micro-line segments is also calculated through speed look-ahead; in each specific micro-line segment, the speed is controlled in different periods, the speed can be changed in real time, and equal-period control is more universal and more flexible; and the pulse uniformity control algorithm is suitable for more complex control fields.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a pulse uniformity control algorithm. Background technique [0002] Electric motors and generators are used in a wide variety of applications and under a wide variety of operating conditions. In general, many modern electric machines have relatively high energy conversion efficiencies, however, the energy conversion efficiency of most electric machines can vary significantly based on their operating load. Many applications require the motor to operate under a wide variety of different operating load conditions, which means that the motor is often not operating as efficiently as it can. [0003] In terms of the response characteristics of the control system, due to its unchangeable nature, the best control system operating point of the analog circuit can only work in the state of DC output or pulse output with fixed frequency, but for variable frequency and duty cycle ...
