Abstract: This thesis is devoted to study four main topics on PID control. Firstly, the relationship on stabilizability of linear time-invariant (LTI) systems by P and PI controllers is investigated. It is found that PI is no poorer than P in terms of stabilization. PI can stabilize all the systems that P stabilizes but the converse is not true in general. Secondly, two simple tuning methods for PID controllers are presented. A framework for PID controller design is presented and it leads to the important popular setting, . Another PID tuning method for dominant pole placement and phase margin specification is also proposed. Thirdly, guaranteed dominant pole placement with PID controllers is achieved with two simple and easy methods, based on the Root-Locus and Nyquist plot respectively. Fourthly, a new design method for internet-based control systems in a dual-rate configuration is proposed. The design achieves load minimization and dynamic performance specifications.
