講演概要: Summary: Automatic control design has been one of the
          major subjects in real-world power system design and is
          becoming much more significant today in accordance with
          increasing size, changing structure, uncertainties and
          complexity. A major challenge in a new environment is to
          integrate computing, communication and control into
          appropriate levels of power systems operation and control.
          In practice, many control systems usually track different
          control objectives such as stability, disturbance attenuation
          and reference tracking with considering practical constraints,
          simultaneously.At the moment in the electric industry applications,
          it is desirable to meet all specified goals using the controllers
          with simple structures. Since, practically these controllers are
          commonly designed based on experiences and trial-and-error
          approaches, they are incapable of obtaining good dynamical
          performance to capture all design objectives and specifications
          for a wide range of operating conditions and various load disturbances.
          It is significant to note that because of using simple structure,
          pertaining to the low-order control synthesis for dynamical power
          systems in the presence of strong constraints and tight objectives
          are few and restrictive. Under such conditions, the synthesis process
          may not approach to a strictly feasible solution.Therefore, the most
          of robust and optimal approaches suggest complex state-feedback or
          high-order dynamic controllers. The present speech addresses systemic,
          fast and flexible algorithms to design of P, PI and PID controllers for
          large scale power systems. The developed strategies attempt to invoke
          the strict conditions and bridge the gap between the power of optimal/
          robust control theorems and industrial power system control design.
