Description
technical field [0001] The invention relates to the technical field of motor drive control, in particular to a motor control device based on DSP servo drive and a control method thereof. Background technique [0002] Motor control is a very important part of the industrial automation process. The application of microprocessors (such as DSP) in the field of motor control has brought a new look to traditional motor control. It has the advantages of fast speed, high control precision, high integration and sensitive response. Existing DSP servo drive devices for motors have poor ability to suppress signal noise, and may easily cause control deviations in some extreme cases. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a motor control device based on DSP servo drive and its control method, which can solve the deficiencies of the prior art and improve the ability of the DSP servo drive device to suppress signal noi...
