Settings of parameters PID controllers with using boths Ziegler - Nichols methods
Bulenínec, Martin ; Burlak, Vladimír (referee) ; Pivoňka, Petr (advisor)
This work deals with adjusting the PID parameters with filtered derivative component and I-PD controllers. The setting is used both methods, of Ziegler and Nichols. Work explains cases of failure of this method. The problem is solved by adding the sampling period due to A/D and D/A converters. Then is searched optimally adjust the controller extension of the sampling period. For the calculation and simulation is used program MATLAB and SIMULINK .
Dead time LTI SISO systems approximation using generalized Laguerre functions
Zsitva, Norbert ; Tůma, Martin (referee) ; Jura, Pavel (advisor)
This final thesis deals with the approximation of time delay in time invariant systems. First, the generalized Laguerre functions and their characteristics are presented. After this, the approximation of the Dirac delta function with the help of these functions is shown. Also, the choice of the free parameters is discussed and the results are evaluated with the help of energy. In the final part of the thesis, the approximations of systems with generalized and simple Laguerre functions are compared.
Possibilities of a dead-time approximation by means of generalized Laguerre functions.
Zsitva, Norbert ; Tůma, Martin (referee) ; Jura, Pavel (advisor)
This bachelor’s thesis deals with the approximation of time delay systems. First, the ways of approximating time delay with rational functions are shown. These methods are evaluated according to the H2 and H norms. After this, the generalized Laguerre functions and means of approximating time delay with these functions are presented. In the final section of the work the previously shown methods are compared.
Modification of 2. Ziegler -Nichols method.
Jaššo, Kamil ; Burlak, Vladimír (referee) ; Pivoňka, Petr (advisor)
This thesis will be focused on verification of usage of time-delay caused by discrete controller's converters for setting it's parameters by Ziegler-Nichols frequency method in cases when this method fails.
