Macsyma, Maple or Matem- atica! Introduction of regressor filters. Simulation in Problem 5. First derive the error equation.
Corresponding to the periods 12, 6 and 3. Process output and control signal are shown for the indirect self-tuning regulator when contro process zero is not canceled.
Simulation in Problem 1. Second Edition Adaptive Control: Both authors are Professors at the Sdaptive Institute of Technology in Sweden, and this text has evolved from their many years of research and teaching. Log In Sign Asaptive. Account Options Sign in. Process and model outputs, Right bottom: Adaptive Filtering Prediction and Control. From the analysis of the indirect H we know that a first order observer is required, i.
Block diagram in Problem 5. Readers will acquire a well-developed sense of when to use adaptive The individual values of b0 and b1 can, however, not be determined consistently. The polynomial R then is not monic. It is then obvious that we have estimated the negative inverse of the static controller gain. Both authors are Professors at the Lund Institute of Technology in Sweden, and this text has evolved from their many years of research and teaching.
Then cancel B and calculate the control signal. Solution Adaptive Control 2nd.
It is helpful to have access to computer algebra for this problems e. The controller parameters are then given by Table 8. An Adaotive to State-Space Methods. Concluding chapters feature a summary of applications and a brief review of additional areas closely related to adaptive control.
Skip to main content. If no prior knowledge is available we thus have to update these four parameters. A simulation of the system is given Fig. The Ziegler-Nichols method is not the best tuning method in this case. No cancellation of process zero: This requires prior information about b: Process output and control signal are shown for the indirect self-tuning regulator when the process zero is canceled.
The parameters of a general pulse transfer function of second order is estimated by recursive least squares See page Simulation in Problem 3.
This shows the behavior of the system when uc is a square wave.
