摘要

本文对这些薄弱环节进行了研究,提出了解决这些问题的建议,并讨论了解决方案的应用以及仿真和实验测试模式下的结果对比。为此,本文考虑对四轮移动机器人进行仿真和实施,并使用线性二次调节器控制器和非线性模型预测控制器对其进行控制。但是,将这些经典和现代控制器与机器学习相结合,可以大大有助于使这些控制器更精确地工作;因此,为了提高这些控制器的性能精度,通过训练多层感知器神经网络,使控制器变得智能化。具有成本函数的控制器有系数作为系统状态变量和控制输入矩阵的权重,改变这两个权重矩阵对问题的解决和优化影响很大。因此,有必要为每条独立路径提取这两个矩阵,以便通过试错来提高控制器的性能。但是,通过采用新算法训练的拟议网络,不仅提高了性能精度,而且网络提取这两个矩阵时无需花费人力物力。同时,为了减少现有的时间延迟,特别是在实验模式下机器人非线性控制器的实现过程中,通过训练其他神经网络来优化提取预测范围的益处,减少了计算量,提高了求解速度。在硬件部分,通过研究和使用像素摄像头和 U2D2 界面等运算器,这些运算器比通常方法更快,从而缩短了求解时间。

Understanding Childhood Victimization Experiences and Mental Health Outcomes in a Sample of Prison Inmates in Northern Chile
In this paper, the weak points have been investigated, the proposal to solve them, the application of the solution and the comparison of the results in the mode of simulation and experimental testing have been discussed. For this purpose, a four-wheel mobile robot has been considered for simulation and implementation, and a linear quadratic regulator controller and a nonlinear model predictive controller have been used to control it. But the combination of these classic and modern controllers with machine learning can greatly help to make these controllers work more accurately; As a result, in order to increase the accuracy of the performance of these controllers, by training neural networks of multilayer perceptrons, the controllers have been made intelligent. Controllers with cost function have coefficients as weighting to the matrix of system state variables and control input, which are greatly affected by changing these two weighting matrices of problem solving and optimization. For this reason, it is necessary to extract these two matrices for each separate path in order to improve the performance of the controller by trial and error. But by applying the proposed network which is trained with a new algorithm, not only the performance accuracy has increased, but the network extracts these two matrices without the need to spend human energy. Also, in order to reduce the existing time delays, especially in the implementation of the nonlinear controller on the robot in the experimental mode, by training other neural networks to optimally extract the benefit of the forecast horizon, reducing the calculations and increasing the speed of the solution has been achieved. In the hardware part, by examining and using operators such as the pixy camera and the U2D2 interface, which are faster than the usual method, the solution time has been reduced.
