Digital control systems for asynchronous electrical drives with vector control principle

A Microcomputer-Based Simulator for Digital Control Systems

A microcomputer-based simulator for digital control systems is proposed. The proposed simulator is a hybrid system in which the plant is simulated by conventional method of analog computers and other parts of the system including generation of input signal is performed digitally, using a Z-80 based microcomputer. To overcome the difficulty of programming in assembly language, and at the same ti...

Pumped Storage Power Plant Control System Modeling by Applying VSI and Vector control principle

This paper includes modeling and simulation of 180 MW units of pumped storage power plant with Variable speed machines. In this method, voltage source inverters are used instead of traditional cyclo-converters. This paper aims to control the voltage source inverters and maintain DC voltage at a constant value. AC/ DC/ AC converter is used in system configuration structure in order to control an...

Control of Electrical Machines for Drives

Electric drive systems are one of the most important components of our life; billions of them are used in industry, traffic applications and private environment. In the recent past an accelerated development of controlled drive systems could be experienced. The scientific and technical background of today’s most important drive systems, the converter controlled DC-drives and the vector controll...

Fuzzy adaptive tracking control for a class of nonlinearly parameterized systems with unknown control directions

This paper addresses the problem of adaptive fuzzy tracking control for aclass of nonlinearly parameterized systems with unknown control directions.In this paper, the nonlinearly parameterized functions are lumped into the unknown continuous functionswhich can be approximated by using the fuzzy logic systems (FLS) in Mamdani type. Then, the Nussbaum-type function is used to de...
