问题：Modelica模型在OpenModelica编译失败（Dymola环境正常）
我用Dymola结合开源库创建了一个Modelica包，包内模型在Dymola中可正常编译与仿真，但在OpenModelica中编译时失败，具体错误信息如下：

解决思路建议
修复变量属性访问问题：
错误核心是OpenModelica尝试读取Integer/Boolean类型变量的nominal/min/max属性，但这些属性是Real类型变量的专属属性，不符合Modelica规范。可以给相关Integer变量显式添加nominal属性（绕过编译器bug）：protected Integer desStep(nominal=1); Integer step(nominal=1); // 其余变量保持不变调整编译参数：
针对开头的线性化阈值警告，添加编译参数--maxSizeLinearization=1000（可根据模型大小调整数值），避免生成有问题的代码。升级OpenModelica版本：
该错误大概率是编译器的版本bug，尝试升级到最新稳定版的OpenModelica，看是否已修复Integer/Boolean变量的属性访问问题。单独调试模型：
先单独编译CompressorStepController模型，确认是否能正常运行。如果单独编译没问题，再逐步集成其他模块，定位冲突来源。检查规范兼容性：
确认模型代码严格符合Modelica规范，比如when语句的触发条件、变量初始化是否合理。例如给nextUpTime和nextDownTime添加fixed=true属性，确保初始值被正确使用：SI.Time nextUpTime(start=0, fixed=true); SI.Time nextDownTime(start=0, fixed=true);
