Temas
Conceptos básicos de los retardos de tiempo
- Especificar retardos de tiempo
Este ejemplo muestra cómo Control System Toolbox™ permite representar, manipular y analizar cualquier modelo LTI con un número finito de retardos.
Retardos de tiempo de los modelos
- Retardos de tiempo en sistemas lineales
Represente retardos de entrada y de salida, retardos de transporte o retardos internos en modelos de sistemas dinámicos. - Closing Feedback Loops with Time Delays
Interconnecting models that have time delays can give rise to internal delays. - Internal Delays
Internal delays can model feedback loops with delays. - Convert Time Delay in Discrete-Time Model to Factors of 1/z
Incorporate input, output, or transport delays as factors of 1/z in a discrete-time model. - Frequency Response Data (FRD) Model with Time Delay
Absorbing time delays into frequency response data can cause undesirable phase wrapping at high frequencies.
Retardos de tiempo aproximados
- Aproximación de retardos de tiempo
Aproximación de retardos de tiempo con filtros de paso total para técnicas de diseño de control que no pueden controlar retardos de tiempo directamente. - Time-Delay Approximation in Continuous-Time Open-Loop Model
Use the Padé approximation to approximate time delays in continuous-time models. - Time-Delay Approximation in Continuous-Time Closed-Loop Model
