d2c

Convert model from discrete to continuous time.

📝 Syntax

• sysc = d2c(sysd)

• sysc = d2c(sysd, method)

• sysc = d2c(sysd, 'prewarp', w0)

📥 Input argument

• sysd - Discret-time dynamic system: LTI model.

• method - Discretization method: 'zoh', 'tustin', 'prewarp'

• w0 - prewarp frequency.

📤 Output argument

• sysc - continuous-time model

📄 Description

The functionsysc = d2c(sysd) transforms a discrete-time dynamic system modelsysd into a continuous-time model, employing zero-order hold on the inputs.

For instance, you can usesysc = d2c(sysd, method) to explicitly define the conversion method.

💡 Example

A = [0.25, 0.5; 0, 0.1];
B = [1; 0];
C = [-1, 0];
sys = ss(A, B, C, 0, 0.2);
sysc = d2c(sys, 'zoh')
