Robust servo system with appointed poles assignment

A small powered gate transistor PWM robust servo system with appointed poles assignment is introduced in this paper. After a brief explanation of the whole system structure and components, emphasis is laid upon the robust design of the DC servo system based on the principle of internal model. With this method symptotic tracing and disturbance rejection of the system are achieved. Digital simulations and experimental steps are then pursued to show the satisfactory performance of the designed system.<<ETX>>
