1. Create a New Model
• By means of clicking on File -> New -> Model, develop a novel model in Simulink.

We require the subsequent elements, to model a lead-lag compensator:

• Sum block
• Step input block
• Transfer Function blocks for the system and the compensator
• Scope block
1. Place Components in the Model
2. Step Input: Direct to Simulink -> Sources from the Simulink library. In our model, we drag the Step block.
3. Sum Block: Generally, into our model, drag the Sum block from Simulink -> Math Operations.
4. Transfer Function (System): In order to depict the plant (system) we need to regulate, drag the Transfer Fcn block from Simulink -> Continuous.
5. Transfer Function (Compensator): For depicting the lead-lag compensator, drag another Fcn block.
6. Scope: Drag the Scope block from Simulink -> Sinks to visualize the output.
7. Connect Components
8. Step Input to Sum Block:
• To the positive input of the Sum block, it is advisable to link the output of the Step block.
1. Sum Block to Compensator:
• The output of the Sum block must be joined to the input of the Transfer Fcn block (Compensator).
1. Compensator to System:
• To the input of the Transfer Fcn block (System), we focus on linking the output of the Transfer Fcn block (Compensator).
1. System to Scope:
• Generally, the output of the Transfer Fcn block (System) should be joined to the Scope block.
1. Feedback Loop:
• To the negative input of the Sum block, the output of the Transfer Fcn block (System) has to be linked back.
1. Configure Components
2. Transfer Function (System): With the transfer function of our system (plant), we construct this block. For instance, the system 1s2+2s+1\frac{1}{s^2 + 2s + 1}s2+2s+11 is depicted by a transfer function with numerator [1] and denominator [1 2 1].
3. Transfer Function (Compensator): Along with the transfer function of our lead-lag compensator, this block should be constructed. Generally, the transfer function could be in the shape of s+z1s+p1⋅s+z2s+p2\frac{s + z_1}{s + p_1} \cdot \frac{s + z_2}{s + p_2}s+p1s+z1⋅s+p2s+z2.

Instance Configuration

In this instance, let’s assume that we have a with the transfer function 1s2+2s+1\frac{1}{s^2 + 2s + 1}s2+2s+11 and we require to model a lead-lag compensator with the transfer function s+2s+5⋅s+1s+0.1\frac{s + 2}{s + 5} \cdot \frac{s + 1}{s + 0.1}s+5s+2⋅s+0.1s+1:

• System (Plant) Transfer Function: Denominator [1 2 1], Numerator [1].
• Compensator Transfer Function: Denominator conv([1 5], [1 0.1]), Numerator conv([1 2], [1 1])
