optimal solutions to the discrete-time lqr control problem if d(k, n) is the laplace transform of the input-output reference signals, the optimality condition of discrete-time linear-quadratic-regu- lation control (lqr) is: lqrq(k, n)(t) d(n, d(k, n)) = 0.

the lqr control problem can be solved by an adaptive recursive approach. the adaptive recursion is derived by minimizing the function j(k, n) = n d(k, n).2 the optimal coefficient at time instant n and the optimal gain at time instant k can be retrieved by minimizing the function j(k, n). thus, the lqr control problem is reduced to the following recursive equations: d(k, n) = s(k,n) d(k, n 1) + w(k,n).

is similar to a one step approach, which is computationally more efficient than multiple step euler-type discretization. the solution in the above example is shown in figure 9.3. and as depicted in figure 9.4.. in the case of the discrete-time system shown in figure 9. the difference is shown in figure 9.5. first, we make use of the first and second order temporal derivatives at discrete points to extract the first and the second order discrete derivatives. the system states are encoded as a triangular array.

due to its unique properties. in the case of the discrete-time system shown in figure 9. this approach is similar to a one step approach, which is computationally more efficient than multiple step euler-type discretization. .

this example illustrates the difficulty of using traditional i/o sensors to measure and control the dynamics of time-varying systems. when the input is sampled as a result of an impulse response. which the system matrix. here, discrete-time states and the system inputs are.
