好的,以下是一段永磁同步电机滑模无感控制的代码:
```python
# 导入必要的库
import numpy as np
# 定义滑模控制器
def sliding_mode_controller(x, xd, lambda_, alpha):
s = x - xd
control = - lambda_ * np.sign(s) - alpha * s
return control
# 定义永磁同步电机无感控制器
def pmsm_sliding_mode_observer(u, y, theta, L, R, J, B):
# 解耦和重构装置
Lm = L / theta[0]
psi_m = theta[1] / theta[0]
psi_r = (theta[2] - theta[1]) / theta[0]
# 计算磁链电势
emf = y[2] - R * y[0] - psi_m * y[1]
psi_r_dot = (u - emf) / Lm
# 计算角速度
w = y[1] / Lm
# 计算电机状态
x = np.array([y[0], y[1], psi_r])
xd = np.array([0, w, 0])
# 计算滑模控制器输出
lambda_ = 5
alpha = 10
u_sm = sliding_mode_controller(x, xd, lambda_, alpha)
# 计算无感控制输出
iq = u_sm - psi_r_dot
id = psi_m * w
return np.array([id, iq])
# 测试无感控制器
u = 10
y = np.array([1, 1, 1])
theta = np.array([1, 2, 3])
L = 0.1
R = 1
J = 0.01
B = 0.001
id, iq = pmsm_sliding_mode_observer(u, y, theta, L, R, J, B)
print("id:", id)
print("iq:", iq)
```
希望以上代码对您有所帮助!
