Abstract:

The paper discusses the application of quasilinearization to the specific problem of determining the parameters in a dynamic model. The model includes parameters related to the system time constants, the gain, and the dead time transportation lag or time delay. The objectives of this study are 1 To show that quasilinearization can be used to determine all model parameters including a dead time transportation lag. 2 To minimize the number of calculations per iteration by a Calculating the solution in terms of parameter changes rather than the parameters themselves, which removes the necessity of calculating the particular solution. b Using the model equation instead of the fundamental solutions to update the output and its derivatives. 3 To investigate various methods to increase the parameter space in which convergence will occur, including a Incorporation of Marquardts Method into quasilinearization. b Only taking a portion of the calculated step.
