Electrical drives are hefty tool have major contribution in most of the industrial and nonindustrial motion control applications. The electrical drive connected through a flexible shaft with a load can be modeled as a two inertia motor system. The proposed work deals with an easy-to-tune controller design strategy for two inertia motor system based on coefficient diagram method. Three speed control...
Design of Proportional Integral and Derivative (PID) controllers based on IMC principles for various types of integrating systems with time delay is proposed. PID parameters are given in terms of process model parameters and a tuning parameter. The tuning parameter is IMC filter time constant. In the present work, the IMC filter (Q) is chosen in such a manner that the order of the denominator of IMC...
The point of this paper is to illustration a speed Controller of a DC motor by decision of a PID parameters using Genetic Algorithm (GAs), the DC motor is widely used as a part of various applications, for example, steel plants, electric trains, cranes and significantly more. DC could be spoken to by a nonlinear model when nonlinearities, for example, interesting dissemination is considered. To give...
In this paper an optimized fractional order proportional, integral and derivative (FOPID) controller is designed to control the non-minimum phase (NMP) systems with time delay. The NMP system shows the undershoot behavior because of having zeros in the right half plane and the response becomes sluggish as the time delay increases. For improving the performance of the NMP system an optimized FOPID...
In this paper the PID controller is designed to control the liquid level in the Spherical tank system (STS). The STS is modeled in fractional order and is approximated to an integer order by using oustaloup's approximation algorithm. The higher order integer system is reduced to a 2nd order by using Balanced Truncation (BT) method. The PID controller is designed for this reduced order model and the...
In this paper an optimized proportional plus integral plus derivative (PID) controller is designed to control the non-minimum phase systems (NMP) with delay. The problem associated with the NMP system is the undershoot behaviour of the system caused by zeros of the right half plane and it becomes trivial as delay increases. To improve the system performance the parameters of the PID controller are...
