提供了基于BP(Back Propagation)神经网络结合PID(比例-积分-微分)控制策略的Simulink仿真模型。该模型旨在实现对杨艺所著论文《基于S函数的BP神经网络PID控制器及Simulink仿真》中的理论进行实践验证。在Matlab 2016b环境下开发,经过测试,确保能够正常运行,适合学习和研究神经网络在控制系统中的应用。 特点 集成BP神经网络:模型中集成了BP神经网络用于提升PID控制器的性能,使之能更好地适应复杂控制环境。 PID控制优化:利用神经网络的自学习能力,对传统的PID控制算法进行了智能调整,提高控制精度和稳定性。 S函数应用:展示了如何在Simulink中通过S函数嵌入MATLAB代码,实现BP神经网络的定制化逻辑。 兼容性说明:虽然开发于Matlab 2016b,但理论上兼容后续版本,可能会需要调整少量配置以适配不同版本的Matlab。 使用指南 环境要求:确保你的电脑上安装有Matlab 2016b或更高版本。 模型加载: 下载本仓库到本地。 在Matlab中打开.slx文件。 运行仿真: 调整模型参数前,请先熟悉各模块功能和输入输出设置。 运行整个模型,观察控制效果。 参数调整: 用户可以自由调节神经网络的层数、节点数以及PID控制器的参数,探索不同的控制性能。 学习和修改: 通过阅读模型中的注释和查阅相关文献,加深对BP神经网络与PID控制结合的理解。 如需修改S函数内的MATLAB代码,建议有一定的MATLAB编程基础。
Great question! If `custom-cart.js` is not working, there are **several ways to debug** and **verify** that your JavaScript is loading and executing correctly. --- ## ✅ Step-by-Step: How to Check if `custom-cart.js` Is Working ### ✅ 1. **Check if the Script Is Enqueued and Loaded** First, make sure your script is **properly enqueued** in your theme’s `functions.php`. #### Example: Enqueue `custom-cart.js` only on the cart page ```php function enqueue_custom_cart_script() { if ( is_cart() ) { wp_enqueue_script( 'custom-cart', get_template_directory_uri() . '/js/custom-cart.js', array('jquery'), null, true ); } } add_action( 'wp_enqueue_scripts', 'enqueue_custom_cart_script' ); ``` #### ✅ How to Confirm: - Open your cart page. - View the page source (right-click → View Page Source). - Search for `custom-cart.js` in the `<head>` or `<body>`. If it’s not there, the script is **not enqueued**. --- ### ✅ 2. **Check Console for JavaScript Errors** Open your browser’s **Developer Tools** (usually `F12` or `Ctrl+Shift+I`), then go to the **Console** tab. Look for: - `Uncaught ReferenceError: jQuery is not defined` - `Uncaught SyntaxError: Unexpected token` - Any other JS errors If there's an error before your code runs, your script may not execute. --- ### ✅ 3. **Add a `console.log()` to Test Script Execution** Add this to the top of your `custom-cart.js`: ```js console.log('custom-cart.js loaded!'); ``` Then: - Open the cart page. - Open the browser console. - If you see the message, the script is **loaded and executing**. --- ### ✅ 4. **Check if jQuery Is Available** Sometimes themes disable jQuery or load it in `noConflict` mode. Wrap your code like this to be safe: ```js jQuery(document).ready(function($) { console.log('jQuery is working!'); // Your code here }); ``` If you see the message, jQuery is working. --- ### ✅ 5. **Check if the Checkboxes Exist When Script Runs** If your checkboxes are loaded **after** the script runs (e.g., via AJAX), then your code won’t find them. #### ✅ Use Event Delegation You’re already doing this — great job: ```js $(document).on('change', 'input[name="selected_items[]"]', function() { // Your logic }); ``` This ensures the event works even if checkboxes are added later. But to test if checkboxes exist: ```js console.log($('input[name="selected_items[]"]').length + ' checkboxes found'); ``` If this logs `0`, your script is running **before** the checkboxes are added to the DOM. --- ### ✅ 6. **Check if AJAX URL Is Defined** Your AJAX request uses `wc_cart_params.ajax_url`. Make sure that is defined. Add this to your script: ```js console.log('AJAX URL:', wc_cart_params.ajax_url); ``` If it’s `undefined`, then `wc_cart_params` isn’t being localized. #### ✅ Fix: Localize Script in PHP In your `functions.php`: ```php function enqueue_custom_cart_script() { if ( is_cart() ) { wp_enqueue_script( 'custom-cart', get_template_directory_uri() . '/js/custom-cart.js', array('jquery'), null, true ); wp_localize_script( 'custom-cart', 'wc_cart_params', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) )); } } add_action( 'wp_enqueue_scripts', 'enqueue_custom_cart_script' ); ``` --- ### ✅ 7. **Check if AJAX Handler Is Working** Add this to your script to see if the AJAX request is sent: ```js $.ajax({ url: wc_cart_params.ajax_url, type: 'POST', data: { action: 'update_selected_cart_items', selected_items: selectedItems }, beforeSend: function() { console.log('Sending AJAX request...'); }, success: function(response) { console.log('AJAX response:', response); }, error: function(jqXHR, textStatus, errorThrown) { console.error('AJAX error:', textStatus, errorThrown); } }); ``` This will show: - If the request was sent - If it succeeded or failed - What the server returned --- ## ✅ Summary: Checklist for Debugging | Step | What to Check | Result | |------|----------------|--------| | 1 | Script is enqueued | ✅ / ❌ | | 2 | Script is loaded | ✅ / ❌ | | 3 | jQuery is available | ✅ / ❌ | | 4 | Checkboxes exist on page load | ✅ / ❌ | | 5 | `wc_cart_params.ajax_url` is defined | ✅ / ❌ | | 6 | AJAX request is sent | ✅ / ❌ | | 7 | AJAX response is received | ✅ / ❌ | --- ## ✅ Bonus: Common Fixes ### ❌ Problem: Script not loading - Solution: Make sure `wp_enqueue_script()` is used properly. ### ❌ Problem: jQuery is not defined - Solution: Make sure jQuery is enqueued before your script. ### ❌ Problem: Checkboxes not found - Solution: Use event delegation (`$(document).on('change', 'selector', ...)`). ### ❌ Problem: AJAX returns 0 or error - Solution: Make sure `wc_cart_params.ajax_url` is correct and your PHP handler is registered. --- ##
