Abstract

Control system performance engineering is aimed at meeting predetermined specifications, for example, accuracy, response speed to steady-state, spike (maximum overshoot) and steady-state error. In general, designers calculate how much Gain is given to the system to obtain a predetermined performance specification. In general, to calculate the Gain is done by using the Trial Error technique. The Pole Placement method explains that a system is said to be stable if and only if the poles of its characteristic equation are to the left of the imaginary axis in the s-plane. Therefore, it is always strived for the location of the poles to have a certain pattern to obtain the desired performance. For a fully controlled system, the selection of the desired pole position can be done arbitrarily through the feedback element. Pole placement can be done using a state feedback control signal. The location and arrangement of the roots (poles) will determine the performance characteristics of a system. To change the performance of a system can be used with state variable feedback (State variable feedback), which can be done easily. To find out how much Gain value is needed, it can be known by using the Pole Placement Method in which the State Feedback Matrix Gain is determined by the T Transformation Matrix, namely by determining the coefficient value of the polynomial characteristic equation of the plant matrix.
