Abstract

The invention discloses a controller for servo motors, which is applied to a servo control system. The controller is characterized by comprising a programmable logic device, wherein the programmable logic device comprises peripheral interface-logic devices, output modulation modules and controlling operation modules, wherein the controlling operation modules are obtained through online programming. According to the controller, the control algorithm of servo motors is implemented by only using the programmable logic device without multiple hardware processors, so that the number of chips is reduced, the weight of a circuit board is reduced, the difficulty of circuit wiring is lowered, and the interface complexity between a main processor and a coprocessor is lowered, so that the cost of the controller is significantly reduced; meanwhile, controlled parameters of each servo motor are subjected to corresponding controlling operation through multiple controlling operation modules in the programmable logic device, so that the operation speed is ensured, and the response speed of a servo system is improved. Therefore, the controller and the control method disclosed by the invention solve the problems in the prior art.

Description

technical field [0001] The present application relates to the technical field of servo control, in particular to a servo motor controller and a control method. Background technique [0002] In the servo control system, the control of the position, speed and current of the servo motor is realized through the servo motor controller. In the prior art, a DSP (digital signal processor, digital signal processor) or a single chip microcomputer is used as the main processor of the servo motor controller to perform position control calculation, speed control calculation and current loop control calculation. Due to the complexity of the above-mentioned control operation process, such as the current loop control operation based on the space vector control algorithm, frequent operations such as multiplication, integration, and differentiation, when it is necessary to control multiple servo motors in the servo control system at the same time, a single DSP or microcontroller It is diffic...
