【Abstract】 The design of a power amplifier for the Movemaster-EX robot was presented. Some key problems were discussed and a method for current control proposed. The motion control experiments were carried out to test the amplifier. The results indicated that the amplifier could meet the control requirements with simple configuration and low cost, and should be helpful to the designs of other systems.更多还原
