선형화 결과의 문제 해결

예상대로 선형화되지 않은 시스템과 블록을 수정하고, 특화된 응용 분야용 블록을 선형화

모델이 예상대로 선형화되지 않으면 Simulink^® Control Design™ 문제 해결 툴을 사용하여 선형화 문제를 진단하고 수정할 수 있습니다. 자세한 내용은 Linearization Troubleshooting Overview 항목을 참조하십시오. 모델 선형기 또는 명령줄에서 모델을 선형화할 때 선형화에 잠재적으로 문제가 될 수 있는 블록을 모델에서 찾을 수 있습니다. 자세한 내용은 Identify and Fix Common Linearization Issues 항목을 참조하십시오.

일부 Simulink 블록은 선형화 결과가 나쁠 수 있습니다. 이러한 블록에 대해서는 일반적으로 사용자 지정 선형화를 지정해야 합니다. 자세한 내용은 Specify Individual Block Linearization 항목을 참조하십시오.

Linearization Troubleshooting Overview

If you do not get expected results when you linearize your Simulink model, you can diagnose and fix potential linearization issues using Simulink Control Design troubleshooting tools.
- Check Operating Point
- Check Analysis Point Placement
Identify and Fix Common Linearization Issues

Troubleshoot Simulink model linearizations using the Linearization Advisor.
Speed Up Linearization of Complex Models
Large Simulink models and blocks with complex initialization functions can cause slow linearization.

사용자 지정 블록 선형화

Specify Individual Block Linearization

Some Simulink blocks, including those with sharp discontinuities, can produce poor linearization results. Typically, you must specify custom linearizations for such blocks.
Specify Custom Linearizations for Simulink Blocks
You can specify a custom linearization for a Simulink block or subsystem that cannot be linearized.
Specify Linearization for Model Components Using System Identification
You can use System Identification Toolbox™ software to identify a linear system for a model component that does not linearize well, and use the identified system to specify its linearization.
Change Perturbation Level of Blocks Perturbed During Linearization
Blocks that do not have preprogrammed analytic Jacobians linearize using numerical perturbation. You can change the perturbation level for your application, which changes the linearization results.

특수한 특성이 있는 모델과 블록

Configure Models with Pulse Width Modulation Signals
Subsystems that contain PWM signals do not linearize well due to discontinuities in the signal.
Models with Time Delays
You can linearize models using exact representations or Padé approximations of continuous-time delays.
Linearize Multirate Models
You can linearize a Simulink model that contains blocks with different sample times.
Linearize Event-Based Subsystems (Externally Scheduled Subsystems)
Since linearization occurs at a specific moment in time, the trigger event for an externally scheduled subsystem never happens.
Linearize Blocks with Non-Floating-Point Signals or States
Blocks that have non-floating-point signals or states and have no preprogrammed exact linearization automatically linearize to zero. Linearizing such blocks requires converting all signals to double precision.
Linearize Simscape Networks
You can linearize models with Simscape™ components using Simulink Control Design software.
