A new Application Specific Integrated Circuit (ASIC) realization of high- performance servo system of four-axis actuators is proposed. This scheme integrates four-axis position loop, velocity loop and current loop on one-chip ASIC. Furthermore, the detail implementations of basic modules such as multiple axis synchronous control strategy, M/T algorithm, Pseudo Derivative Feedback +Feedforward (PDFF)...
A high-performance digital servo system realized on the platform of field-programmable logic array (FPGA), permanent magnet synchronous motor (PMSM) and encoder is proposed. The intact vector control strategy of PMSM is described with Verilog hardware description language (HDL) and implemented on one-chip FPGA in accordance with the EDA design methodology. This realizes the high density and miniaturization...
