Each autonomous technological process requires an early fault detection system as an integral part of its infrastructure. Complex fault diagnostics system must be able not only to quickly detect any unwanted deviation from nominal function, but also to make a competent estimate of the type and source of possible failure. The article presents the fault diagnostics system based on Markov model. It uses...
This paper introduces a simple technique extending possibilities of the relay feedback identification. The approach enables to estimate five parameters of the transfer function from a single test using an asymmetric relay to generate sustained oscillations. The method offers a tool for a large class of common control problems. The applicability of the suggested simple technique is demonstrated by...
Design and principle of Mendocino motor. Speed of Mendocino motor is controlled via intensity of incident light. The halogen lights voltage is changed using PWM. A device called “Control unit” is designed to set the PWM, measure speed of Mendocino motor and communicate with computer. Software Matlab Simulink is used to create different approaches to control Mendocino motor, with using Matlab S-function...
Currently used stability criteria for linear sampled-data systems refer to the standard linear difference equation form of the system model. This paper presents a stability criterion based on the argument increment rule modified for the delta operator form of the sampled-data model. For the asymptotic stability of this system form it is necessary and sufficient that the roots of the appropriate characteristic...
