AC servo system has undergone a transition from analog to digital, and the digital control loop is now ubiquitous, such as commutation, current, speed and position control; new power semiconductor devices, high performance DSP plus FPGA, andservo dedicated modules are available. International manufacturers of servo products will be replaced every 5 years, the newpower devices or modules every 2 to 2.5 years will be updated once, the new software algorithms are changing, in short, the product life cycle is getting shorter and shorter. In recent years, domestic and foreign manufacturers have introduced the exchange of servo motion control of newtechnologiesand new products, such as closed-loop AC servo drive technology, linear motor drive technology, PCC technology,based on th...
