D$when designing controller. Substituting$u=-Kx$into cost function, it becomes$$J=J = \frac{1}{2}\int_0^{T} x^T(Q+K^TRK)x dt$$inorder to found$K$, we assume that there exists one constant matrix$P$which statisfy$$\frac{d}{dt}(x^TPx)=-x^T(Q+K^TRK)x$$Put this ...

LQR控制器是常见的最优控制器,它的主要特点是将控制量加入到了成本函数中。 对于线性系统: x ˙ = A x + B u \dot x = Ax+Bu x˙=Ax+Bu 设计控制器 u = − K x u = -Kx u=−Kx使得 J = 1 2 ∫ 0 ∞ x T Q x + u T R u d t J = \frac{1}{2}\int_0^\infty ...
在我们的PSOLQR本地路径规划器的设计中,我们采用了一种解耦的规划和控制架构。规划和控制算法的核心过程分别在pso_optimizer.cpp和lqr_controller.cpp中实现。这些组件提供了保留的接口,可快速轻松地访问规划和控制功能。这种模块化方法可以方便地更改规划或控制算法,而无需重新设计本地规划器,提供了出色的可扩展性。

I need control this model with LQR controller. I implemented the cost function with: x=[Pm w] u=[a] where, Pmis manifold pressure, wis the speed and a is the trhottle angle. Firststep I have linearized the model with: [a b c d]=linmod('Engine'); ...

Hi, first of all thank you for your hard work, this control toolbox on python has been very hepfull. I've been using the LQR function in order to compute a K gain for my system but the size of it doesn't match the expected size. See my s...
