在控制系统中,相角裕度和幅值裕度通常达不到预期标准,因此,需要对其进行一定的校正,而串联超前校正是我们常用的校正方法之一;我们通常是随机选择一个角频率ω_c进行校正,若校正后的相角裕度和幅值裕度达不到要求,则需要重新选择一个角频率ω_c进行计算,这便导致反复进行多次计算,而且所选的剪切频率ω_c也不一定是最优解,更不能知道所选的最大范围;为了简化计算步骤,在此引入了基于MC算法的控制系统的校正,通过产生随机替代上述繁琐过程,并根据评价函数找出最优值,对控制系统的校正有一定参考价值。
In the control system, the phase margin and the amplitude margin usually can not reach the expected standard, therefore, it needs some correction, and the tandem lead correction is one of our commonly used correction methods; we usually choose one at random If the corrected phase margin and amplitude margin do not meet the requirements, a new angular frequency ω_c needs to be selected for calculation. This will result in repeated calculations and the selected cut The frequency ω_c is not necessarily the optimal solution, but also can not know the maximum range selected. In order to simplify the calculation steps, the control system based on the MC algorithm is introduced to correct the system. By randomly substituting the tedious process above and finding out the evaluation function The optimal value, the control system calibration has some reference value.
