摘　　要：基于ＬＱＲ理论设计的最优快关控制由于下列原因使其效果受到限制：（１）故障初期的严重模型失配；（２）过高的反馈增益使得控制量受到严重限幅。该文提出将线性最优快关控制和开环快关控制相结合，克服了前述缺点。The effectiveness of the optimal control of fast valving designed according to LQR theory is limited because of the following reasons:(1)severe model mismatch in preliminary period of breakdown;(2)too high feed back gains making control variable restricted severely. This paper presents the combination of linear optimal control of fast valving with open loop control which overcomes previously described shortages and improves control effectiveness greatly.
