This thesis first provides a new methodology for all the current available control system design methods. Based on the new methodology, the Ideal Control System Design Method (ICSDM) is then developed. This is a feasible and simple method to achieve a desired system design. This method takes two and a half loops of control spaces, the inner and outer loops plus the open loop, the semi-loop. It can design a system as ideal as the designer desires. The inner and outer loops are structurally similar. They provide the system the capability of system dual self-protecting. The inner loop protects the plant from any kind of the disturbances and constrains the plant to behave according to a mandatory controller which is used to define the model of the plant. The outer loop provides the dual protection to the system and constructs a desired system, i.e., ideal system transfer function by means of properly choosing the structural parameters of K, Fx and F2. The design is simple because all the circuit blocks are functionalized so that a simple and clear space of the system is presented. Using the ICSDM, "input follower" system, i.e., the system output equals the input, has been designed. Simulation results are presented and agree with the mathematical derivations very well. The results are also compared with those of the negative feedback control and the ITAE standard forms for optimal control. The comparison verifies the system designed by the ICSDM has perfect performance and also possesses complete robustness, high sensitivity to the input commands, and insensitivity to any disturbances.
