2. 1. Multivariable Frequency-Domain Identification of Industrial Robots

   Author : Erik Wernholt; Svante Gunnarsson; Jan Swevers; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency-domain identification; industrial robots; nonparametric identification; nonlinear gray-box identification; multivariable systems; closed-loop identification; Automatic control; Reglerteknik;

   Abstract : Industrirobotar är idag en väsentlig del i tillverkningsindustrin där de bland annat används för att minska kostnader, öka produktivitet och kvalitet och ersätta människor i farliga eller slitsamma uppgifter. Höga krav på noggrannhet och snabbhet hos robotens rörelser innebär också höga krav på de matematiska modeller som ligger till grund för robotens styrsystem. READ MORE

4. 2. On Multivariable and Nonlinear Identification of Industrial Robots

   Author : Erik Wernholt; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The main objective of the thesis is the identification of flexibilities and nonlinearities in mathematical models of industrial robots. In particular, a nonparametric frequency-domain estimation method for the multivariable frequency response function (MFRF) has been evaluated and analyzed for the robot application. READ MORE

5. 3. Identification of State-Space Models from Time and Frequency Data

   Author : Tomas McKelvey; Lennart Ljung; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This dissertation considers the identication of linear multivariable systems using finite dimensional time-invariant state-space models.Parametrization of multivariable state-space models is considered. A full parametrization, where all elements in the state-space matrices are parameters, is introduced. READ MORE
