分析了γ-SGPC在保证控制性能的情况下，使参数调节更加直观的策略不具有一般意义。找到了其不适用的情况，通过对此算法的改进，消除了γ—SGPC算法适用情况的局限性。通过预测误差来校正γ增益的大小，达到降低控制误差和增强抗扰动性能的目的。对某机组的主汽温对象进行了仿真，取得良好的控制效果，证明了该算法的有效性。

The strategy of making parameter adjustment more intuitionists under condition of guaranteed γ-SGPC control performance is found to have no common sense. The un-applicable situation is defined. By calculation method improvement, the applicable limitation problem of γ- SGPC algorithm is eliminated. It is achieved by predicting the error to proofread the value of γ gain to reduce control error and improve anti-disturbance performance. Simulation for main steam temperature of 300MW unit is conducted, and upstanding control result is obtained, and the validity of calculation method is proved.
