Induction motors (IM) attracted many researchers in the last few decades. In this field, various applications are implemented, such as servo motor drives and electric vehicles. This work applies a sensorless direct torque controller (DTC) to control three-phase IM. System dynamics of IM were derived. A nonlinear dynamic model had introduced with white noise. Given complexity dynamics, Jacobean ...

Classical proportional-integral-derivative (PID) control is exploited widely in industrial motion systems with dry friction motivated by the intuitive and easy-to-use design tuning tools available. However, classical PID suffers from severe performance limitations. In particular, friction-induced limit cycling (i.e., hunting) observed when integral employed on frictional that suffer Stribeck ef...

This article is devoted to the fuzzy fault-tolerant tracking control of Markov jump systems with unknown mismatched faults. To reconstruct faults and system states, a sequence proportional–integral observers are established via outputs. With help structure separation technique, gains observer solved by unified linear matrix inequality framework. Resorting rebuilt states from an iterative estima...

Adaptive observers were first introduced by Carroll and Lindorff in [1], and later on modified by Kudva and Narendra in [2]. For a more detailed analysis and design of adaptive systems see [3], [4], [5]. In many applications where the parameters are unknown and states are not accessible, adaptive observer appears to be a valuable method in estimation of both parameters and states of the system....

Direct current (DC) motor speed control is useful. Speed can be modified based on needs and operations. DC motors cannot their speed. To the motor’s speed, a dependable controller needed. The will controlled by fuzzy logic proportional integral derivative (FLC-PID). circuit’s electrical mechanical components have been modeled mathematically. Ziegler-Nichols used to tune PID controller’s gain pa...
