Mathematical Modeling of Control Systems 2–1 INTRODUCTION In studying control systems the reader must be able to model dynamic systems in math-ematical terms and analyze their dynamic characteristics.A mathematical model of a dy-namic system is defined as a set of equations that represents the dynamics of the system. the optimal decisions are given by the arrows leaving each box in every column of Fig. (c). The method of computation illustrated above is called backward induction, since it starts at the right and moves back one stage at a time. Its analog, forward induction, which is also possible, starts at the left and movesforward onestage ata Size: 2MB.

Dynamic behavior of the machine under both transient and steady state conditions. This chapter presents two approaches for developing the mathematical model of the induction motor. Induction Motor Modelling: A dynamic model of the machine subjected to a control must be known in order to understand and design the vector controlled Size: KB.

This book is a comprehensive reference source for practicing engineers and students specializing in electric power engineering and industrial electronics. It will illustrate the state of the art in induction motors. Beginning with characteristics and basic dynamic models of induction motors, and progressing to low- and high- performance drive systems.5/5(1).

The principle of vector control of AC machine enables the dynamic control of AC motors, and induction motors in particular to a level comparable to that of a DC machine. discrete-time model of system (it must be as accurate as possible), and numerical optimization.

An optimal sequence of input actions over the whole prediction horizon is precalculated with respect to optimal future behavior of system. Receding or moving horizon control (RHC) is a basic feature of MPC ensuring a feedback control: only the first.

Vector control is a method for dynamic control of the speed torque and power factor of the induction motor through permanent control of the intensity and the angle of the space vectors of the.

Abstract. In the chapter issues related to the application of the Model Predictive Control (MPC) to position control of a drive system with an induction motor (IM) coupled to a load machine through a long shaft are : Piotr Serkies, Krzysztof Szabat.

The induction motor model developed may be used alone, as in the direct-on-line starting. It can be incorporated in an advanced motor drive system, e.g. field oriented control. It is also helpful in designing of induction motor according to the requirement.

Mainly due to power electronics and digital control, the induction motor may add to its old nickname of “the workhorse of industry” the label of “the racehorse of high-tech”.

A more complete list of events that marked the induction motor history follows. • Better and better analytical models. The proposed novel dynamic reference model is really a further application of MRAC theory in induction motor drive systems, which realizes the real-time control.
