本文主要包括以下两个方面的工作： 1以梁的动力学方程为基础，推导了梁的波动模型以及弹性波的能流强度和梁振动能量的关系，最后应用二范数理论确定了控制器的补偿函数。 - Abstract : a bandgap voltage reference is presented with a piecewise - linear compensating circuit in order to reduce the temperature coefficient . the basic principle is to divide the whole operating temperature range into some sub - ranges . at different temperature sub - ranges the bandgap reference can be compensated by different linear functions . since the temperature sub - range is much narrower than the whole range , the compensation error can be reduced significantly . theoretically , the precision can be improved unlimitedly if the sub - ranges are narrow enough . in the given example , with only three temperature sub - ranges , the temperature coefficient of a conventional bandgap reference drops from 1 . 5 10 - 5 / to 2 10 - 6 / over the - 40 to 120 temperature range
文摘:提出了一种采用分段线性补偿的方法来实现高精度带隙基准,其基本原理是将整个温度区间分为若干个子区间,在不同子区间上采用不同线性补偿函数达到最佳补偿.由于温度区间缩小,补偿误差也随之减小,从而在整个工作温度间上的补偿误差也缩小.理论上,只要温度子区间取得足够小,就可以达到任意精度.示例中将- 40 120的温度区间仅分为三个子区间,平均温度系数就从1 . 5 10 - 5 /减小到2 10 - 6 / - The three control systems respectively were as follows : ( 1 ) the measuring part of the first one was displacement piezoelectric sensor . a pair of piezoelectric sensor / actuator was collocated by each side of the first solar array plate . the compensator was h ( s ) = 2395 - s ; ( 2 ) the measuring part of the second one was also displacement piezoelectric sensor . a pair of piezoelectric sensor / actuator was collocated by each side of the whole solarfan . tthe compensator was h ( s ) = 244s ; ( 3 ) the measuring part of the third one was velocity piezoelectric sensor . a pair of piezoelectric sensor / actuator was collocated by each side of the three solars array plates near to the body of satellite
三种控制系统分别是： ( 1 ) 、采用压电位移传感器，压电传感器驱动器对同位布置于内板的边缘，控制器补偿函数为h ( s ) = 2395s ~ ( 1 2 ) ； ( 2 )采用压电位移传感器，压电传感器驱动器对同位布置于整个太阳帆板的边缘，这是一种理想的情况，控制器补偿函数为h ( s ) = 244s ~ ( 1 2 ) ； ( 3 )采用压电速率传感器，压电传感器驱动器对同位布置于靠近星体的三块基板边缘，控制器补偿函数为h ( s ) = 2370s ~ ( 1 2 ) 。 - Optimal periodic control with the lowest operational cost by limiting total substrate discharge mass was studied . through adding new state variable and using supplement functions , the problem with restriction conditions was converted into nonrestriction problem . in addition , the dynamic searching method of optimal step coefficient was developed to modify the conventional gradient method , consequently the calculation problem of the multivariable optimal periodic control was able to be resolved better . it was found that the operational costs of optimal control under various initial states are distinctly different . a new concept of optimal control under optimal initial state was presented . it is pointed out emphatically that to the treatment system without optimal control condition , the suboptimal control with extensive practical value can be realized according to the results of optima control
着重研究了在限制有机物排放总量时，使其运行费用最低的最优周期控制问题.通过增加新的状态变量和用补偿函数法，将本课题的有约束条件问题化为无约束条件问题，并提出了最优步长参数的动态搜索法来修改传统的梯度法，从而较完善地解决了多变量最优周期控制的计算问题.研究中还发现了不同初始条件下最优控制所需要的运行费用也大不相同，进而提出了最优初始状态下最优周期控制的新概念，这对保证出水质量的同时进一步降低污水处理成本来说具有更重要的意义.本文还强调指出：对于尚不具备实现最优控制条件的处理系统，可根据最优控制的研究结果实现具有广泛实用价值的准最优控制
