Discrete Feedback Systems 2.

Modern Control


State-feedback control

In contrast to the design techniques which are based on the transfer function of a system in this section we would discuss the state-space methods of designing stabilizing controllers. Pole placement is a very powerful tool for stabilization. We have already discussed how feedback controllers can be designed for the system given in transfer function form, using the Root-Locus method. This method allowed calculation of the parameters of a PID-type controller such that the poles of the closed loop system are placed in desired positions in the z-plane corresponding to the desired closed loop performances.

The classical control theory and methods that we have been presented in the first volume are based on a simple input-output description of the plant, expressed as a transfer function, limiting the design to single-input single-output systems and allowing only limited control of the closed-loop behaviour when feedback control is used. Typically, the need to use modern linear control arises when working with models which are complex, multiple input multiple output, or when optimization of performance is a concern. Modern control theory revolves around the so-called state-space description. The state variable representation of dynamic systems is the basis of different and very direct approaches applicable to the analysis and design of a wide range of practical control problems. To complete the design workflow, finally some introduction into system identification theory is given.
