Library
The library consists of six blocks for individual models and methods that can be easily used by copying in new schemas.Block description
The block consists of two inputs and two outputs. At the input we bring the input to the identified system u and the output from the identified system y. The output of the block is the estimated value of the system output and the theta vector parameters.Block parameters
Various parameters can be entered in the block mask.- order of system - for corretct identification it is necessary to know order of idendificated system
- delay - transport delay of idendificated system
- estimated theta - starting values of estimated parameters (implicit value is zero), size of vector depends on order of system (e.g. order is 2, size of theta is 4)
- estimated covariance matrix - starting values of covariance matrix (implicit value is eye matrix of 1000), size should be the same as size of vector theta
- forgetting type - switch for the types of forgetting
- forgetting factor lambda - implicit value 0.95, active for mentioned forgetting types
- forgetting factor phi - implicit value 1, active only for adaptive direcional forgetting
- forgetting factor ypsilon - implicit value 0.00001, active only for adaptive direcional forgetting
- forgetting factor ro - implicit value 0.99, active only for adaptive direcional forgetting
- vector forgetting factor omega - implicit value 1.05, size of vector is the same as size of vector theta, active only for exponential forgetting matrix
- order of system - for corretct identification it is necessary to know order of idendificated system
- delay - transport delay of idendificated system
- estimated theta - starting values of estimated parameters (implicit value is zero), size of vector depends on order of system (e.g. order is 2, size of theta is 4)
- estimated covariance matrix - starting values of covariance matrix (implicit value is eye matrix of 1000), size should be the same as size of vector theta
- memory of instrumental variable - size of memory, should be biger then order of systemx2
