Embodiments provide techniques, computer-readable media, and devices for allowing users to perform interactive design of controllers, such as PID controllers, in a free-form modeling environment. Users can tune controllers using characteristics familiar to typical users rather than having to specify gain values for the controller, which may be difficult for a user to relate to the performance of a controller.

Automated PID controller design, using parameters that satisfy a merit function

A tool for analyzing a sequence of data in an object-oriented environment is disclosed. In an embodiment, the sequence of data may include time-indexed sequence of data ('time series data'). The tool may provide graphical user interfaces that enable a user to analyze the time series data encapsulated in a time series object or time series collection object. The graphical user interfaces may enable a user to create a time series object and manipulate the data in the time series object or time series collection object. The graphical user interfaces may also display the data in the time series object or time series collection object in various types of plots, such as time plots, spectral plots, x-y plots, correlation plots and histograms.

Graphical user interface for analysis of a sequence of data in object-oriented environment

A tool for viewing data in a software environment is disclosed. The data may be a multi-dimensional data set. The viewer tool provides various features for viewing and exploring the data set. The viewer tool may be coupled to a test environment that generates data from the tests of a unit under test (UUT). The data may be generated from one or more sequences of tests that can be divided into batches. The viewer tool may receive the data from the test environment and analyze the data to provide a user with useful information on the data. The viewer tool may display the data with the information so that the user can obtain the information on the data. In particular, the viewer tool may enable the user to understand the relationship between the measured test data and the various test conditions under which the test data has been measured.

Viewer for multi-dimensional data from a test environment

A tool for analyzing a sequence of data in an object-oriented environment is disclosed. In an embodiment, the sequence of data may include time-indexed sequence of data ('time series data'). The tool may enable a user to generate a time series object for encapsulating the time series data in the object-oriented environment. The user may construct the time series object from data or mathematical expressions using a command line interface. The time series object may include a sequence of objects implementing APIs that supply an interface for analyzing the times series data in the time series object. The user may analyze the time series data encapsulated in the time series object using the APIs of the time series object.
