Direct current servocontrol system design
Abstract:Along with technical development in electronics in electric power and its applied technical advances, single the super-speed development of a machine, make the direct current servocontrol control technique show remarkable advance .It introduced in the text with MCS — 51 single a machine is work principle and hardware design projects of the servo system in direct current to control the core.Combine to emphasize the software design that introduced thought and design methods of the direct current servocontrol system, it included the design of the main procedure, give the design that settle the procedure, modify the design of the procedure and start the design of the procedure to break off the design of the procedure with the T0, passing to the fixed amount with comparison and PIDs that feedback measures control procedure, output the certain electric voltage, realize system opposite angles degree of accurate follow.
