“…After identification by this method obtained parameters are satisfactory, but not precise.

Commonly we used such kind of synthesis method, which the control loop response should be on the aperiodic border (this is the "best" quality of control loop response).…”

“…Known Strejc method suitable for this task is well described in [3]. It is unnecessary to describe the derivation of two transcendental equations (4), (5) in detail, which form the basis of the method. The precondition from which this method was derived is that transient characteristics intersect at one point, as can be seen from the transient characteristics in Fig.…”

To identify the parameters from the transient response, on proportional second order process when in the numerator is the only gain, and the characteristic equation have two different time constants, the Strejc's method, which is generally known, is used most commonly [3]. After identification by this method obtained parameters are satisfactory, but not precise. But exact parameters are needed for the verification of digital control algorithms, especially for its real-time verification [4], [5]. Commonly we used such kind of synthesis method, which the control loop response should be on the aperiodic border (this is the "best" quality of control loop response). If the actual response will be with overshooting or it's too damping, we need to determine which errors causes this If we know that the identification is correct, then the errors can be easier found.

This paper describes two methods for realization of configurable time continuous linear and non-linear dynamical models. The first method is based on classical PC plus A/D and D/A converters and the second one is based on a microcontroller (Atmel ARM7). Both methods can be used for verification of algorithms for control and identification of processes, modeling of transport processes dynamics using simulation experiments, if simulations run in real time. The application of a microcontroller allows a simple realization of changing parameters and also non-linearity of the process. In the paper we also pay attention to the realization of real time in a programmable environment under Microsoft Windows and the realization of precise calculations in floating point on microcontrollers.
