“…Because the stability control of the DC side voltage is very important for the SVG co mpensation effect, considering the disadvantages of the traditional PID control with fixed parameters and the poor adaptability [32][33][34][35][36], the paper introduces the PSO algorith m with global search performance into the PI parameters optimizat ion. The paper takes the SVG voltage loop as the controlled object, and the voltage loop transfer function is deduced.…”

The operation flow of particle swarm optimization (PSO) is presented, at the same time the PSO algorithm and GA algorith m are used to find the optimal value of the standard function, simu lation results show that the PSO algorith m has better global search performance and faster search efficiency. The inertia weight decreasing strategy of PSO algorith m is studied, the simulation results show that the concave function decreasing strategy can accelerate the convergence rate of the algorithm. The stability control of the DC-side voltage is very important for the static var generator (SVG) co mpensation, but the disadvantages of the traditional PI control are fixed parameters and poor adaptability of dynamic response, PSO algorith m is introduced to the optimizat ion of PI parameters, so online PSO-PI control and off-line PSO-PI control are obtained, the SVG voltage loop transfer function is used as the controlled object. The simulat ion results show that the PSO-PI control can satisfy the time varying system of the controlled object with strong adaptability.

UAV avionics system is prone to saturation distortion under unsteady conditions, so anti-saturation control is needed. A control method of UAV avionics system based on anti-saturation feedback compensation is proposed. The anti-saturation control process of UAV avionics system is a multi-objective optimization process with multi-variables. The constrained parameter model of UAV avionics system control is constructed. Electromagnetic loss, torque, output power and other parameters are taken as constraint indexes, the original control information of UAV avionics system is treated with self-stabilization, the equivalent control circuit is designed, and the magnetic resonance transmission mode of avionics system is analyzed. An anti-saturation feedback tracking control method is used for steady-state control of the output voltage of the avionics system. The error compensation function is constructed to adjust the output adaptive parameters of the avionics system and the static anti-saturation compensator is constructed to compensate the power gain. The yaw error and the output steady-state error of the avionics system are reduced. The simulation results show that the proposed method has better output stability, lower output error, better real-time performance and better linear auto-disturbance rejection control performance.

“…Their observations are useful for system level mechanical design but do not provide the quantitative measures needed for performance-critical controller design. Between these two extremes lie a wealth of methods which produce control parameters given a stability margin [7,8,12,[21][22][23][24]. Other criteria serving a similar purpose include the use of integrated absolute error, maximum sensitivity, Lyapunov-based stability, and others [14,15,25,26].…”

This paper introduces a simple and effective method for selecting the maximum feedback gains in PD-type controllers applied to actuators where feedback delay and derivative signal filtering are present. The method provides the maximum feedback parameters that satisfy a phase margin criteria, producing a closed-loop system with high stability and a dynamic response with near-minimum settling time. Our approach is unique in that it simultaneously possesses: (1) a model of real-world performance-limiting factors (i.e., fil-tering and delay), (2) the ability to meet performance and stability criteria, and (3) the simplicity of a single closed-form expression. A central focus of our approach is the char-acterization of system stability through exhaustive searches of the feedback parameter space. Using this search-based method, we locate a set of maximum feedback parameters based on a phase margin criteria. We then fit continuous equations to this data and obtain a closed-form expression which matches the sampled data to within 2–4 % error for the majority of the parameter space. We apply our feedback parameter selection method to two real-world actuators with widely differing system properties and show that our method successfully produces the maximum achievable nonoscillating impedance response.
