Linear Time Invariant System or abbreviated with LTI System is a composition of several components that form a linear system configuration with input-output characteristics that do not change with time. This thesis aims to design an optimal control solution for Linear Time Invariant system that minimizes performance index by determining the exact and matrix values. LTI system used in writing this thesis is a dynamic system with a continuous time that has been done to convert the system into the form of state space equation. The optimal control design on LTI system with quadratic linear type consists of 2 problems, namely regulator and tracking problem. Regulatory problem solving aims to stabilize the system with variable / output to remain small with Linear Quadratic Regulator (LQR) control technique. While solving the tracking problem aims to force the output of the system so that the output produced in accordance with the desired trajectory by using Linear Quadratic Tracking (LQT) control technique. The result of the discussion on the problem especially for regulator problem will be applied in the form of MATLAB program simulation by taking model of car suspension system which the model equation has been converted into state space equation.
