多变量前馈控制
摘要：
一种在瞬变工况中追踪燃气涡轮发动机的变量状态的方法(200)包括：获取代表转子速率和压力比的输入数据(210)；基于输入数据来计算基准瞬变计划轨迹(220)；基于输入数据来计算速度基准瞬变计划轨迹；基于基准瞬变计划轨迹来计算前馈变量(230)；获取反馈控制变量(240)；和基于前馈变量和反馈控制变量的组合来确定控制变量(250)。
摘要（英）：

A method (200) of tracking variable states of a gas turbine engine in transient conditions includes obtaining input data (210) representative of rotor velocity and pressure ratio; calculating a reference transient scheduled trajectory (220) based on the input data; calculating a speed reference transient scheduled trajectory based on the input data; calculating a feedforward variable (230) based on the reference transient scheduled trajectory; obtaining a feedback control variable (240); and determining a control variable (250) based on a combination of the feedforward variable and the feedback control variable.
