Realization of a Non Integer Order PID Controller
نویسندگان
چکیده
In this paper a new PID controller is presented. Its peculiarity consists in the non integer order of the derivative and integral, being this order variable in the range [0,1], and providing two further parameters to the controller. The key element is a Multi-layer Perceptron that evaluate a non integer order integration. The neural network approach allows to overcome some problems related to practical implementation of the circuit. A hardware realization of a non integer PID controller is also reported.

This paper proposes a novel fractional order PID controller for torsional system’s backlash vibration suppression control, in which the order k of D controller can not only be integer but also be any real number. Various methods have been proposed for two-inertia system’s speed control, but the control systems designed by these methods may not be able to suppress the vibration caused by gear ba...

متن کاملControl quality enhancement by fractional order controllers
PID controllers belong to the dominating industrial controllers (Leššo, 1997) and therefore there is a continuous effort to improve their quality and robustness. One of the possibilities to improve PID controllers is to use fractional order controllers with non integer derivation and integration parts. The controlled objects are generally of fractional order, however for many of them, the fract...
