This paper presents a comparative study of two most popular control strategies for Induction motor (IM) drives: FieldOriented Control (FOC) and Direct Torque Control (DTC). The comparison is based on various criteria including basic control characteristics, dynamic performance, and implementation complexity. The study is done by simulation using the Simulink Power System Block set that allows a...

This paper presents a personal computer (PC)-based data acquisition and control tool that uses a Peripheral Interface Controller (PIC) microcontroller, Matlab, and Simulink. Specifically, a library of PIC microcontroller functions for Simulink is created. Moreover, the PIC microcontroller and Matlab are merged, by exploiting their serial communication capability, to produce an inexpensive data ...

The automotive industry is in the process of broadly adopting a new model-based approach for embedded systems development. However, the available tools still have a number of deficiencies, particularly with respect to the modelling of large and complex systems. This article discusses the present support for decomposition and dataabstraction in SIMULINK and outlines future needs. Keywords— model...

ClawZ is a prototype tool whose objective is to link the Simulink control engineering tool, from MathWorks, with the dialect of Z. It provides a bridge between the use of Simulink to define control law diagrams and a tool to formally prove compliance between Ada and Z. The tool has been used as part of the formal proof of a Non-linear Dynamic Inversion flight control system comprising 37 pages ...

We present a compositional semantics and analysis framework for hierarchical block diagrams (HBDs) in terms of atomic and composite predicate transformers. Our framework consists of two components: (1) a compiler that translates Simulink HBDs into an algebra of transformers composed in series, in parallel, and in feedback; (2) an implementation of the theory of transformers and static analysis ...

This paper presents modeling of a discrete DC motor positioning using system identification. The identification of most suitable discrete model of DC motor was done by using MATLAB/Simulink. The best discrete model was determined by testing with four different sampling times. Result presented shows that the best model achieved performance of 87.79% at 55ms sampling time. Key-Words: System ident...
