![精确复刻这张深度学习海报，整体版式、配色、字体、所有元素位置和未提及的文字内容完全保持不变，只做以下两处修改：
修改一（第4部分实战：图像分类）：
1. 最右侧"识别结果示例"板块中，四张图片（飞机、汽车、猫、狗）下方的置信度百分比文字全部删除，只保留类别名称（飞机(airplane)、汽车(auto)、猫(cat)、狗(dog)）
2. 中间的正确率板块：将"使用了Dropout技术"这段文字移动到板块的最上方；将原来的正确率提升部分的文字改为"过拟合现象显著改善"；该板块的上下两部分文本字体大小保持一致
修改二（第3部分训练与优化）：
最右侧箭头指向的数学公式框内的内容，将原有的"delta4 = a4.(1-a4).(a4-y(:,k))"替换为新的公式：δ[l] = D[l](W[l+1]TD[l+1](W[l+2])T ... D[L-1](W[L])TD[L](a[L]−y). ，数学公式字体大小保持不变，如果公式长度不够显示则自动换行。公式框的样式和大小不变。
除以上修改外，海报的其他所有内容、文字、布局、配色、元素均与原图完全一致，不得做任何其他改动。](https://gd-cms.dancf.com/gd-cms/xi19e5/0/3530c86a-efbd-407d-9b00-6ac90e9c99a624739.jpeg?x-oss-process=image/resize,w_640,type_6/sharpen,120/interlace,1)

1. 在RESEARCH BACKGROUND板块之前新增一个板块，标题为"Abstract"，完整添加以下内容：
To address two core issues in sliding mode current control for permanent magnet synchronous motors—first, that sliding mode chattering limits control accuracy, and second, the inherent trade-off between chattering suppression and disturbance rejection—this paper proposes a second-order terminal sliding mode control scheme based on a super-twisting reaching law.
In the design of the sliding surface, a first-order integral fast terminal sliding surface is embedded into a second-order nonsingular terminal sliding surface structure. This combined design retains the chattering suppression advantage of the former while achieving the fast convergence characteristic of the latter when the system state is near the equilibrium point, and it avoids the singularity problem.
In the design of the reaching law, the super-twisting sliding mode algorithm is introduced to further mitigate chattering and achieve fast convergence of the currents with steady-state-error-free tracking.
Finally, simulation verification is conducted and compared with conventional control methods. The results demonstrate that the proposed scheme offers significant advantages in improving current dynamic response, suppressing chattering, and enhancing disturbance rejection capability.
2. 新增一个板块标题为"Core Method Framework"，完整添加以下内容（全部英文）：
■ Proposed Control Scheme: STA + STSMC
▎Sliding Surface Design — Second-Order Non-Singular Terminal Sliding Mode Surface
Embed the first-order integral fast terminal sliding surface into the second-order non-singular terminal sliding surface structure:
First-order sliding variable: s_{1d} = e_d + \int (c_{ed} \cdot e_d + c_{td} \cdot e_d^{\alpha/\beta}) d\tau
Second-order sliding variable: s_{2d} = s_{1d} + c_{nd} \cdot (\dot{s}_{1d})^{m/n}
Where:
• e_d = i_d^* - i_d is the d-axis current tracking error
• α, β are positive odd numbers, satisfying α < β
• m, n are positive odd numbers, satisfying 1 < m/n < 2
• c_{ed}, c_{td}, c_{nd} are positive coefficients
Design Features:
✓ Retains the chattering suppression advantage of the first-order integral fast sliding mode
✓ Has the fast convergence characteristic of the second-order non-singular terminal sliding mode near the equilibrium point
✓ Avoids the singularity problem
▎Reaching Law Design — Super-Twisting Algorithm (STA)
Super-twisting sliding mode reaching law expression:
\dot{s} = -p \cdot |s|^{1/2} \cdot \text{sign}(s) + y
\dot{y} = -i \cdot \int \text{sign}(s) dt
Nonlinear control term:
u_{sw} = L_0 \cdot [ p \cdot |s|^{1/2} \cdot \text{sign}(s) + \int i \cdot \text{sign}(s) dt ]
Design Advantages:
✓ Introduces the sign function into the integral term of the control voltage, which is beneficial to chattering suppression
✓ Ensures fast convergence of sliding variables in finite time
✓ Achieves zero-static-error current tracking
3. 保持画面比例为16:9横版学术海报，调整整体布局保证协调。
4. 新增一个板块标题为"Simulation Verification Results"，完整添加以下内容，并将提供的两张对比曲线图[image2]和[image3]并排嵌入此板块，图片整体缩小，两张图片总面积不超过整个海报面积的1/10，保持图片清晰：
Simulation Verification and Comparative Analysis
Experimental Conditions:
• Motor speed: 3000 r/min
• d-axis reference current: i_d^* = -50 A (constant)
• q-axis reference current: i_q^* steps from 20A to 87A at t=0.02s
• Comparison target: conventional exponential reaching law SFTSMC vs. the proposed STA+STSMC
Main Conclusions:
• The proposed scheme reduces the control voltage chattering amplitude to less than 1/3 of the conventional scheme at rated speed
• Effectively solves the problems of low steady-state accuracy and large current fluctuation caused by large chattering in traditional sliding mode current control
• Ensures that the motor current state can track the reference signal in finite time
