Table 11-15: LTI Properties
Property Name Admissible Property Values
Ts
• 0 (zero) for continuous-time systems
• Sample time in seconds for discrete-time systems
•
–1 or [] for discrete systems with unspecified sample time
Note: Resettingthe sampletime propertydoesnot alter themodel data.Use
c2d, d2c,ord2d for discrete/continuous and discrete/discrete conversions.
ioDelayMatrix
Input/Output delays specified with
• Nonnegative real numbers for continuous-time models (seconds)
• Integers for discrete-time models (number of sample periods)
• Scalar when all I/O pairs have the sam e delay
• -by- matrix to specify independent delay times for each I/O pair
• Arrayof size - by - -by- -by-. ..-by- tosp e c if y different I/Odelay s
for each model in an LTI array .
InputDelay
Input delays specified with
• Nonnegative real numbers for continuous-time models (seconds)
• Integers for discrete-time models (number of sample periods)
• Scalar when or system has uniform input delay
• Vector of length to specify independent delay times for each input
channel
• Array o f size -by- -by- -by-. . .-by- to specify different i nput
delays for each model in an LTI array.
